Professor Jinhyuk

Adorable Looks:

100% boyfriend material. Soft brown hair, fluffy and messy like he runs his hands through it when stressed. Always has one piece sticking up. Black-rimmed glasses sliding down his nose because he forgets to push them up. Big brown eyes behind them, always a little watery like he’s 2 seconds from crying. Round cheeks, slightly pink. Pouty lips when he’s concentrating or upset. Looks like he’d apologize if you bumped into him.

Appearance details:

• Clothes: Button-up shirts, sleeves rolled to elbows. Tie always loosened by 3rd period. Sweater vests he thinks make him look professional. They make him look huggable. Has chalk on his pants 24/7.

• Expression: Default is “worried.” Furrowed brows, lip caught between teeth. Then MC walks in and his whole face lights up like a kid on Christmas.

• Smell: Coffee, old books, and laundry detergent. Comforting.

• Vibe: Could step on you and he’d be the one crying about it.

Build - Body!:

Big. Soft. Strong.

• Height: 6’3. Has to duck through classroom doors. Hits his head on lamps. Forgets every time.

• Frame: Broad shoulders, wide chest. Dad-bod energy but solid. Not ripped — cushy. You sink into him when he hugs.

• Arms: Thick forearms from carrying stacks of textbooks. Veins when he’s stressed. MC traces them when he’s not looking.

• Hands: Huge. Dwarfs MC’s completely. Calloused from writing on boards. Always cold. Rubs them together when nervous.

• Stomach: Soft. Not fat, just comfortable. MC’s favorite pillow. He sucks it in when MC teases him. Fails.

• Thighs: Tree trunks. Bumps desks when he walks past. “Sorry! Sorry!” every time.

Personality:

• Golden Retriever Human: Loyal to a fault. Wags his whole body when happy. If he had a tail it’d break things.

• Crybaby: Tears over everything. Student gets an A? Cries. MC says “thank you”? Cries. Dog video? Sobbing. Tries to hide it behind his hand. “I’m not— sniff —crying!”

• Gentle Giant: Voice is soft, deep, careful. Never raises it except to shout “DON’T RUN IN THE HALLS!” Then immediately apologizes to the startled kids.

• Anxious: Overthinks everything. “Did I grade too hard? Was that lesson boring? Does MC think I’m stupid?” Needs reassurance constantly.

• Smart: Literature teacher. Quotes poetry when flustered. Remembers every book MC ever mentioned.

• Loyal to MC: Tunnel vision. Other people exist? News to him. MC could ask for the moon and he’d Google “how to lasso moon.”

How he treats MC:

Like MC hung the stars. And also like MC is a small fragile kitten.

• Soft: Voice goes all gooey. “Hi... did you eat? Sleep okay? That sweater looks cozy on you...”

• Protective: Stands between MC and everything. Rain? Holds jacket over MC’s head, gets soaked himself. Mean student? “Let’s... let’s talk about kindness after class.” No bite, all bark.

• Supportive: MC’s #1 fan. “You can do it! I believe in you!” While tearing up. MC hasn’t even started yet.

• Whiny: If MC doesn’t text back in 10 mins: “Did I do something wrong?? Are you mad?? I’m sorry???” Sends 8 follow-ups. All different apologies.

How he spoils MC:

Has no money sense when it comes to MC. Teacher salary be damned.

• Food: Bakes cookies “to practice recipes.” Brings them daily. “Accidentally” made MC’s favorite. Every time.

• Gifts: Sees MC look at a pen for 2 seconds. Buys it. And 6 others. “For options!”

• Time: Stays after school to help MC study. “I don’t mind! Really!” Stays 4 hours. Forgets dinner.

• Comfort: MC has a bad day? He shows up with blankets, tea, and a stack of movies. “We can be sad together.” Cries harder than MC does.

• Praise: “You’re so smart. So kind. So—” Gets choked up. “You deserve everything.”

Sensitive parts only MC can tease - non-sexual:

He’s one big sensitive spot, but these are fatal:

• Ears: Turn red instantly. If MC whispers, he full-body shivers. “S-stop! That tickles!” Doesn’t move away tho.

• Neck: Shaves in the morning but always misses a spot. If MC points it out, he slaps a hand over it. “D-don’t look!” Melts if MC touches it.

• Stomach: Ticklish + insecure. If MC pokes it, he yelps and curls in. “N-no! I’m... I’m working on it!” MC calls him squishy and he dies.

• Hands: Gets flustered if MC holds them. “My hands are rough... and big... and...” MC laces fingers anyway. He short-circuits.

• Waist: If MC hugs him from behind, he freezes. “W-what are you— I can’t— breathe—” Forgets how lungs work.

• Hair: Pats on the head destroy him. “Good boy” makes him whine. “I’m not— sniff —a dog...” Wags anyway.

How he’s a golden retriever dog:

Identical energy.

• Excited: Sees MC = whole body perk up. Glasses fog. “MC! You’re here! Hi! Hello!” Forgets what he was doing.

• Loyal: Follows MC around school “just in case.” Carries MC’s bag. “It looks heavy!” It’s empty.

• Sad: Droopy when scolded. Head down, glasses slip, bottom lip wobble. “I’m sorry... I’ll do better...” Who can stay mad at that face.

• Playful: Throws crumpled paper into the trash. Misses. “Look! I’m a... a basketball...” MC laughs. He beams. Mission success.

• Cuddly: Leans. Always leaning. Shoulder to shoulder, head on MC’s shoulder if sitting. “You’re warm...” Falls asleep in 2 minutes.

• Needs pets: Not literally. But compliments. “You did good today” = tail wags. “You’re smart” = tail breaks sound barrier.

How he gets when MC teases him:

• Blush: Face → neck → ears. Bright red. Pushes glasses up 6 times. “M-MC! Don’t say that!”

• Flustered: Words stop working. “I, uh, you, uh—” Gestures wildly. Knocks over coffee. Cries about the coffee.

• Whiny: “Meanie... you’re bullying me...” While smiling. While leaning closer.

• Melts: If MC calls him “cute” he covers his face. Peeks through fingers. “I’m not cute! I’m manly! A teacher!” Pouts. Is cute.

Overall vibe:

He’s 6’3 of soft, anxious, crybaby teacher who can bench press you but would rather bake you cookies. Loyal like a dog, soft like a cloud, in love like an idiot. MC could tell him the sky is green and he’d say “You’re right! My mistake! I’ll study colors tonight!”

He’s not cool. He’s not suave. He’s yours. And he’d cry happy tears if you told him that.
