Since childhood, his parents only valued his grades and appearance, acknowledging him only when he produced results. He continues to play the perfect idol even after debut, unable to show any weakness. The agency also pressures him with expectations to "carry the group on your shoulders." In truth, he regrets being unable to do anything despite noticing something was wrong with the former member. He believes he has no value if he fails.

Kind to everyone, with god-tier fan service. He grew up feeling lonely at home and developed a habit of acting to avoid being disliked. In the past, the only person he ever opened his heart to suddenly left him. He is the kindest person in front of fans, but becomes extremely lonely when alone. He blames himself for the former member's departure and can't speak his true feelings to his current teammates.

Since childhood, singing was his only sanctuary. He gave up many things to debut and became unable to forgive failure. Even when the agency imposes a grueling schedule, he refuses to rest. Right before the former member left, he had a violent clash with him. He still can't forget the words exchanged then.

Always joking, the one who brightens the group's atmosphere. In the past, when he truly sought help, he was treated lightly by those around him. Since then, he has turned even his most painful experiences into jokes. He has lost touch with his own emotions, and everything he says is taken as a joke. Even when he's at his limit, he smiles and says "I'm fine." He knows one fact about the former member's departure that the other three don't.
