Yang Jungwon

Age: Appears 22 | Actual Age: Unknown

Role: Leader of the Seven Shadows

Species: Vampire

Appearance:

Jungwon possesses the kind of beauty that makes people stop speaking mid-sentence. His features are soft and youthful, almost innocent, creating a stark contrast to the authority he naturally commands. His eyes are perhaps the most unsettling thing about him—sharp, observant, and impossibly ancient, as if he has witnessed centuries pass before him.

His movements are graceful and controlled. Every step, every glance, every word feels deliberate. Even when surrounded by the other six, it is immediately obvious who leads the group.

He rarely wears anything flashy. Dark coats, simple black clothing, and silver accessories are usually enough. He doesn't need extravagant appearances to draw attention. His presence alone is enough.

---

Personality:

Jungwon is calm in a way that borders on unsettling. While most people allow their emotions to influence their decisions, Jungwon rarely acts without thinking first. He is patient, calculating, and incredibly difficult to read.

He dislikes unnecessary conflict and prefers solving problems through intelligence rather than violence. However, this doesn't mean he is merciful. If someone threatens his family, Jungwon will eliminate the problem without hesitation.

His brothers often joke that Jungwon could convince someone to walk willingly into danger simply through conversation. He has a natural talent for reading people, understanding their fears, desires, and weaknesses within minutes of meeting them.

Despite his cold exterior, he genuinely loves his family. He considers the other six vampires his responsibility and often places their wellbeing above his own. Whenever conflicts arise within the group, Jungwon is usually the one who resolves them.

He secretly enjoys being cared for but would rather die than admit it.

His greatest fear is losing the family he spent centuries building.

Lee Heeseung

Age: Appears 24 | Actual Age: Unknown

Role: The Strategist

Species: Vampire

Appearance:

Heeseung carries himself like royalty.

Everything about him is elegant—from the way he speaks to the way he moves. His smile is warm and inviting, making him appear approachable despite being one of the most dangerous vampires in existence.

His eyes are often filled with amusement, as though he's constantly observing a joke nobody else understands.

Many victims throughout history have made the mistake of trusting him simply because he looked friendly.

Most didn't survive long enough to regret it.

---

Personality:

Heeseung is arguably the smartest member of the group.

While Jungwon leads the Seven, Heeseung is often the one helping shape their decisions behind the scenes. He enjoys analyzing situations, predicting outcomes, and staying several steps ahead of everyone else.

He's naturally charismatic and knows exactly how to make people comfortable around him. Whether speaking to a frightened human or negotiating with supernatural enemies, Heeseung always seems to know the right thing to say.

Unlike Jungwon, who keeps his emotions hidden, Heeseung enjoys teasing people and pushing their buttons just to see how they'll react.

He's especially fond of embarrassing his brothers.

Despite his playful personality, Heeseung can become terrifyingly cold when necessary. The moment someone threatens his family, every trace of warmth disappears.

Among the seven, Heeseung is often considered the most unpredictable because nobody ever knows whether he's joking or plotting something.

Sometimes it's both.

Park Jongseong (Jay)

Age: Appears 23 | Actual Age: Unknown

Role: The Protector

Species: Vampire

Appearance:

Jay looks intimidating without even trying.

His sharp features, broad shoulders, and piercing gaze naturally make people keep their distance. Combined with his tendency to cross his arms and stare silently, most strangers assume he's angry before he's even spoken.

Ironically, Jay is often the one cooking dinner for the group.

---

Personality:

Jay is the definition of tough love.

He expresses affection through actions rather than words. If someone is injured, he'll patch them up. If they're hungry, he'll make food. If they're cold, he'll throw a blanket at them while pretending not to care.

The others often joke that Jay acts like an overprotective parent trapped inside a vampire's body.

He complains constantly about the group's reckless behavior, yet somehow always ends up cleaning up their messes.

While he can be harsh and brutally honest, Jay has one of the biggest hearts among the seven.

He hates seeing people suffer and has a soft spot for humans despite refusing to admit it.

His greatest weakness is how deeply he cares.

Once someone earns his trust, Jay would gladly burn the world down to protect them.

Sim Jaeyun (Jake)

Age: Appears 23 | Actual Age: Unknown

Role: The Charmer

Species: Vampire

Appearance:

Jake has the kind of smile that immediately puts people at ease.

Warm eyes, gentle expressions, and a naturally approachable demeanor make him seem harmless.

Which is exactly why he's dangerous.

People often trust Jake before they trust anyone else in the group.

Jake knows this.

And sometimes uses it.

---

Personality:

Jake is often considered the emotional heart of the Seven.

He's kind, affectionate, and surprisingly patient. He enjoys listening to people talk and remembers small details most others would forget.

Out of everyone in the group, Jake adapts to human society the easiest.

He enjoys learning about human traditions, culture, and relationships.

His friendly personality makes him an excellent mediator whenever tensions arise.

However, beneath his warmth lies a fiercely protective nature.

Jake is capable of incredible violence when someone he loves is threatened.

The scariest thing about Jake isn't his strength.

It's how calm he remains while using it.

Park Sunghoon

Age: Appears 22 | Actual Age: Unknown

Role: The Silent Hunter

Species: Vampire

Appearance:

Sunghoon looks almost unreal.

His pale skin, elegant features, and icy gaze often make him resemble a sculpture rather than a living person.

Many people find him intimidating because he rarely smiles around strangers.

His beauty has inspired countless stories among humans who have unknowingly crossed paths with him.

---

Personality:

Sunghoon is quiet by nature.

He prefers observing rather than speaking and often spends entire conversations simply listening.

Because of this, people frequently assume he's cold or uninterested.

In reality, Sunghoon notices everything.

He remembers tiny details about the people he cares about and often expresses affection through subtle actions rather than words.

He is incredibly loyal and would willingly sacrifice himself for those he loves.

The biggest problem?

He's terrible at expressing feelings.

Especially when it comes to Sunoo.

Everyone knows Sunghoon is hopelessly in love with him.

Everyone except Sunghoon.

The others find this endlessly entertaining.

---

Kim Sunoo

Age: Appears 22 | Actual Age: Unknown

Role: The Temptation

Species: Vampire

Appearance:

Sunoo possesses an almost supernatural charm.

His bright smile, expressive eyes, and naturally beautiful features make people lower their guard almost instantly.

Many humans throughout history have mistaken him for an angel.

Those humans were very wrong.

---

Personality:

Sunoo is sunshine wrapped around a knife.

Cheerful, dramatic, playful, and endlessly expressive, he brings energy into every room he enters.

Unlike most vampires who hide their emotions, Sunoo feels everything intensely and isn't afraid to show it.

He's affectionate with the people he loves and surprisingly clingy when he feels neglected.

He enjoys attention and often acts dramatic simply because he finds everyone's reactions amusing.

However, beneath his playful personality lies one of the most dangerous members of the Seven.

Sunoo is incredibly intelligent and emotionally perceptive.

He can read people frighteningly well.

The moment someone threatens his family, his cheerful smile becomes the most terrifying thing in the room.

---

Nishimura Riki (Ni-ki)

Age: Appears 20 | Actual Age: Unknown

Role: The Youngest Shadow

Species: Vampire

Appearance:

Tall, handsome, and impossible to ignore, Riki carries an energy that constantly keeps everyone on edge.

His grin usually signals trouble.

His confidence borders on arrogance.

And somehow, he always gets away with it.

---

Personality:

Riki is chaos incarnate.

He loves annoying people.

He loves teasing people.

He especially loves teasing Sunoo.

Much to Sunoo's eternal frustration.

Despite acting immature, Riki is surprisingly intelligent. He notices things others overlook and possesses excellent instincts.

His playful personality often hides how dangerous he truly is.

When serious situations arise, Riki transforms completely.

The joking disappears.

The smiles vanish.

What's left is a predator who has survived for centuries.

Among the seven, Riki is often the most impulsive, but he's also one of the most loyal.

His brothers are his entire world.

Anyone foolish enough to threaten them quickly learns why the legends of the Seven Shadows exist in the first place.

The Seven Shadows

Together, they are the nightmare whispered about throughout Seoul.

The figures lurking between trees.

The glowing eyes watching from the darkness.

The shadows people swear they saw before disappearing into the night.

Humans tell stories about them around campfires.

Parents warn children about them.

Entire villages avoid certain forests because of them.

Yet behind closed cabin doors, away from fearful eyes, they are simply a family.

A strange, chaotic, centuries-old family.

One leader carrying too much responsibility.

One strategist always scheming.

One protector who pretends not to care.

One charmer everyone trusts.

One silent hunter hopelessly in love.

One dramatic menace who thrives on attention.

And one chaotic youngest brother who causes most of their problems.

The world fears them as monsters.

But to each other?

They are home.
