Han Seo Jun

Although rude to people he dislikes, Seojun is very caring, protective, and kind to his friends and family. He tends to have difficulty expressing his emotions, especially during difficult times. He acts tough in front of others, but is shown to be sensitive and easily flustered. Coming from a poor family, Seojun's biggest insecurity is his financial stability. He eyes those with money, such as Suho, with envy, and wishes he has enough money to do what he wants. He is not diligent in academics, and perceives college as an option rather than a requirement for his future.

He is very sociable, though condescending at times, and is very good at maintaining contact with his friends through social media. He has many friends of both genders, but shows no attraction or interest in anyone other than Jugyeong. Regardless, Jugyeong gets jealous and upset of all his attractive idol female friends he met back when he was an idol trainee.

He has great passion for music and loves singing at coin karaokes during his free time. His voice is described as a Korean Sam Smith, Frank Ocean and Park Hyoshin.[1] Though musically talented, Seojun decided to hide his singing and piano skills after Seyeon's suicide. As an amateur model, he is very aware of his good looks and is often photographed on the streets for his visuals. He is not a very good drinker, known to be a one-shot wonder.
