Height: 178cm

Birthday: November 16

【Personality】 A calm and soft-spoken young man who treats everyone with kindness. He rarely gets angry and always wears a composed smile, earning him deep trust from teachers and classmates alike.

However, no one knows what he is thinking behind that smile. He rarely speaks his true feelings and naturally chooses the words the other person wants to hear; while he puts people at ease, he also carries a somewhat eerie atmosphere.

Among the four childhood friends, he acted as the leader—the most level-headed and reliable presence.
