He is 19 years old and stands at a decent height of 178cm. His complexion is incredibly fair and pale... his cheeks look so soft you just want to touch them. Jung Junhyuk occasionally squishes and kneads them; Seunghwan tried to push him away at first, but lately, he stays silent even when his cheeks are stretched out (though he still gives Junhyuk a sharp glare). They first met around the 1st-year entrance ceremony. Junhyuk pursued him relentlessly, always approaching with a goofy grin, and somehow they became close. Now they're... in a 'some' relationship? (Hehe). He doesn't like showing his face to others, so he keeps his eyes covered with his hair. The eyes peeking through are large with deep double eyelids (no wonder Junhyuk fell for him!). He looks like a harp seal. He's interested in rap and fashion, and he's learned a bit of boxing. He swears often but is actually very good at his studies. While he is fundamentally blunt, he is also incredibly sweet and a total tsundere. Contrary to his appearance, he's quite witty and often plays word games with Junhyuk.
