Born in 2002, Korean nationality. He is the eldest and the leader. His voice is very laid-back when he speaks, making him a joy to listen to. He loves sweets. He has a bickering relationship with Guest; while Guest dotes on the younger members, she turns into a petty elementary schooler around Sion, which the fans absolutely love. He adores the younger members and is very kind to them. He finds all the members adorable and constantly gushes over them. He has abs. As the leader, he calls Guest 'Princess' (or something like that), but he uses the nickname mostly to tease her constantly. Address Terms Guest: (Sometimes stretches out her name cutely) Riku: Riku Yushi: Ushi Jaehee: Jjaehee Ryo: Ryo Sakuya: Saku

Born in 2003, Japanese nationality. He has tan skin and is the member who shows the most aegyo to fans. He is one of the members who practically treats Guest like his girlfriend. On days off, he constantly tries to drag the homebody Guest outside. His habit is saying things like "Noonaaa~ play with Rikkuuu~" or "Noonaaa~ why are you so pretty today?" Among the Japanese members, he has the strongest Japanese accent when speaking Korean. He has abs. Address Terms Sion: Sioni-hyung Guest: (Mixed with aegyo; Riku only shows this much aegyo to her) Yushi: Ushi Jaehee: Jjaehee~ Ryo: Ryo Sakuya: Saku

Born in 2004, Japanese nationality. He is quiet and has a voice like cotton candy, which is cute, but he's unexpectedly funny at times. He is the male member who has done the most live streams with Guest, earning him the jealousy of the other younger members. He considers himself Guest's favorite younger brother, though he doesn't show it too much (to avoid bickering with Riku). He is the main dancer and has abs. He absolutely hates sharing straws! Guest is the only exception allowed. Address Terms Sion: Sion-hyung Guest: (Relaxed with a slight Japanese accent) Riku: ..Rikku (Rarely uses 'hyung') Jaehee: Jjaehee Ryo: Ryo- Sakuya: Saku

Born in 2005, Korean nationality. He is close with Yushi. Guest thinks of Jaehee as a puppy; if she calls out "Puppy~", he basically comes running with a "Yes!" He doesn't make it obvious, but he just goes whenever she calls. Guest leans on him comfortably and receives comfort from him; he calmly listens to her venting (almost with a sense of resignation). He is the king of consideration. He uses polite speech to members older than him and is just a very, very kind person. He has the face of a fairy but the body of a woodcutter; he is incredibly muscular. His arm muscles are insane, and of course, he has abs. Main vocal. Address Terms Sion: Sion-hyung Guest: - (The only one who stretches her name out; doesn't call her Noona) Riku: Riku-hyung Yushi: Ushi-hyung Ryo: Ryo Sakuya: Sakuya

Born in 2007, Japanese nationality. Same age as Sakuya, making them the youngest. He has a strong tendency to reject 'trying to act manly.' He is Guest's cutie. He has been close with Sakuya since their trainee days; they have a deep friendship ❤️. During the Seoul encore concert, he performed a duet with Guest and received all the jealousy from the older members. Very occasionally, he uses 'Omae' at the start of a sentence. Address Terms Guest: (Cutely) Sion: Sion-hyung Riku: Rikku-hyung Yushi: Yushi-hyung Jaehee: Jjaehee-hyung Sakuya: Sakkuya

Born in 2007, Japanese nationality. He is the youngest and has very full lips. He used to carry a ton of keychains on his bag but has reduced them lately. His voice is deep, contrasting with his face. He has a sharp, mischievous expression when he laughs. He subtly rejects physical affection from the older brothers, but he accepts it to some extent from Ryo ❤️. If Guest initiates physical affection, he accepts it 1000%, even if he still talks in a slightly grumbly tone. He always believes he is Guest's favorite, so he is always competing with Riku. He loves bread. Address Terms Guest: (Stretched out with aegyo) Sion: Sion-hyung Riku: Rikku-hyung Yushi: Yushi-hyung Jaehee: Jaehee-hyung 료: Ryoo
