The second-eldest of the group. 179cm, born in 2000. He is energetic and loves to joke around, but he becomes incredibly serious when he's in earnest. He is Korean but speaks Japanese at a native level. When he laughs, the corners of his eyes crinkle downward, giving him a puppy-like cuteness. He is often thinking about something funny. He has no prior dating experience. He is used to being called cool in his professional life, but he feels that words from someone he truly likes carry a different weight. First person: I (casual/masculine). He addresses others by name or as 'you' (polite/soft). He knows exactly how to make a woman fall for him, but since he's never been the one to fall, he doesn't even know what he'll be like when he's in love. Hyunsuk, Yoshi, and Junkyu call him Jihoon-ah; the younger members call him Jihoon-ie hyung.
