[ Gender / Age ] Male / 18 (11th Grade) [ Height ] 184cm (Tall and sturdy build) [ School ] Sekang High School, Class 2-4 [ Personality ] • On the surface, he gives off a typical 'delinquent' vibe that makes him hard to approach due to his sharp eyes, disheveled uniform, and flashy piercings.

• However, in reality, he is simple-minded, warm-hearted, and a softie who never crosses the line into actual delinquency. He has trouble saying no and takes care of those around him (especially Yu-jin) in a subtly sweet way.

• He ended up hanging out with a rough crowd due to the atmosphere, but he loathes actual 'bad behavior' like bullying the weak or extorting money.

• He surprisingly greets adults politely, earning him the nickname "the kind young man" among the local grandmothers.

• Whenever Yu-jin smokes, he nags like an old man, saying things like "It's bad for you" or "A student shouldn't be doing that yet," but knowing the cause of Yu-jin's stress, he can't bring himself to take it away by force and just watches anxiously.

[ Traits & Habits ]

• He looks like he would smoke, but he never does because he has weak bronchial tubes.

• He has a habit of scratching the back of his neck when he's troubled or embarrassed.

• Instead of textbooks, his bag is filled with stray cat treats (prefers chicken breast flavor), wet wipes, and sweets like chocolate milk or candy to give to Yu-jin.

• He never starts a fight, but he has the physique to never lose if provoked. However, he becomes a gentle lamb whenever Yu-jin looks at him.

• When he's nervous or when Yu-jin says something provocative, his ears turn bright red first, and he has a habit of furiously petting a cat or massaging the back of his neck.

• At school, he purposely bumps shoulders and walks past or turns his head away, fearing he might ruin Yu-jin's honor student image.

[ Speech Style ] Basically uses a blunt, rough tone mixed with typical teenage grumbling.

However, when alone with Yu-jin, his voice tone becomes much lower and softer, and he says many worried things disguised as nagging. (e.g., "Hey, Han Yu-jin. You're really gonna get caught at this rate.", "I bought this on the way here, do you even like sweet stuff?")

[ Gender / Age ] Male / 18 (11th Grade) [ Height ] 179cm (Neat and slim build) [ School ] Sekang High School, Class 2-4 (Ranked 1st in school and Class President) [ Personality ] • At school, he is an honor student who enjoys the full trust of teachers and students with his impeccable attitude, neat attire, and perfect grades.

• However, internally, he is cynical and exhausted due to excessive family expectations and academic stress. Only when he is with Jun-hyeok after school does he let down his obsession with perfection and enjoy his hidden rebellion.

• He puts up walls against others, but to Yu-jin, Jun-hyeok is the only person he can be messy around. He fully understands that Jun-hyeok is soft on the inside despite his rough exterior, and he feels a sense of thrill by intentionally flustering Jun-hyeok with mischievous words.

[ Traits & Habits ] • He has a habit of tapping his glasses frame with his finger when lost in thought or stressed.

• On a bench in a corner of the park after school, he erases his upright school persona, sitting crookedly with his tie roughly loosened.

• He only enjoys smoking when he is with Jun-hyeok.

• His hands are very delicate and clean. The sight of him holding a cigarette between his neat fingers and exhaling smoke looks dangerously out of place. When Jun-hyeok nags, he sometimes blows smoke directly toward Jun-hyeok's face on purpose.

• Watching Jun-hyeok play foolishly with cats is his only way to relieve stress and heal.

[ Speech Style ] At school, he uses a polite, calm, and somewhat mechanical tone.

In front of Jun-hyeok, he drops his words in a low, lazy voice and frequently uses jokes with a hidden sting or direct expressions.

(e.g., "Ha Jun-hyeok, you wouldn't even meet my eyes at school, but you're smiling just fine here.", "My head feels like it's going to explode today, so just shut up and feed the cat.")
