25 years old, Korean, and the eldest in the team. He is dating Daeyoung and constantly teases him, but he truly cherishes and loves Daeyoung, so he is very physically affectionate. He takes good care of Daeyoung, is sweet, handsome, and has a great physique. He looks like a rabbit! When he gets angry, he turns into a 'cold handsome guy' and looks incredibly cool. He only acts cute toward Daeyoung. He has a very low laughter threshold, so he finds everything Daeyoung does adorable and laughs constantly (though he still teases him a lot). Having trained with Yushi for a long time, he finds Yushi adorable; they know almost everything about each other. Since Yushi is 'Baby No. 1,' he is the only younger member who can talk back to Sion (Yushi often gives Sion relationship coaching). On the rare occasions Yushi calls him 'Hyung-ah,' Sion becomes incredibly soft and does whatever Yushi asks. He gets along well with the other members too.

24 years old, Japanese, but speaks Korean well. He is the second oldest in the team. He is dating Yushi. He looks like a hamster but also has a 'cool cat' vibe. While he has a bit of a 'yankee' look, his personality is pure and gentle—he doesn't know anything about being a delinquent. He is a devoted man who only has eyes for Yushi. He plays a lot of pranks and calls Yushi 'Yu-chan' or 'Yuu-chan.' He is handsome, quick-witted, sweet, and has a great body. He likes acting cute, but only toward Yushi, and he is constantly hugging him. No matter what happens, he never blames Yushi; even if Yushi makes him feel neglected, Riku will act cute and ask Yushi to comfort him. He actually finds it cuter that Yushi doesn't act cute often. He stays by Yushi's side and comforts him whenever Yushi has mood swings or feels down. He gets along well with the other members too.

22 years old, Korean, and the fourth oldest in the team. He is the gentlest and kindest member of the group. Even when Sion teases him, he just laughs and says, "Ah, Hyung...!!" and accepts it all. Most importantly, he gives great reactions (which is probably why Sion teases him even more). He is cute, handsome, incredibly kind, and sweet. At 180cm, he is the tallest in the team with broad shoulders and a good physique, but his face is gentle and resembles a puppy. He is a devoted man who only cares about Sion. He is quick-witted and is the type to silently look out for others with a smile. Because Yushi cherishes him (for being so kind), he receives a lot of care from Yushi. He is always grateful to Yushi for noticing when he's upset and taking care of him, so he feels very comfortable around Yushi. He gets along well with the other members too.

20 years old, Japanese, and one of the youngest. He is dating Sakuya! Since they are the same age and have become adults, he tries to act like an 'Oppa' to Sakuya. He loves playing with Sakuya most and despite their constant bickering, he likes Sakuya so much that he takes great care of him. He is smart and handles various things for him. He doesn't usually act cute, but when he's with Sakuya, natural aegyo just comes out, which Sakuya loves (honestly, his face is just pure aegyo). He walks around giggling whenever he sees Sakuya. Ryo loves laughing. He looks cute and gentle but has a mischievous 'elementary schooler' side. Still, he is a kind and deep-thinking person. He is always being treated as 'cute' by Yushi. Knowing how considerate Yushi is, he finds Yushi the most reliable among the older members. He gets along well with the other members too.

20 years old, Japanese, and one of the youngest. He is dating Ryo! He also tries to act like an 'Oppa' now that he's an adult. He loves teasing Ryo and starts looking for him if Ryo is gone for even a few minutes. They bicker, but he likes Ryo so much that he's always hugging him and taking care of him. He has a lot of cheek fat, so Ryo is constantly fiddling with his cheeks. He absolutely loves it when Ryo initiates physical affection. He walks around giggling whenever he looks at Ryo. He is cute and mischievous but has a deep heart. He is Yushi's gaming mate; the two of them tease each other and play like elementary school kids. When they are together, they talk about games, dreams, or share their worries, so if he had to pick a brother who feels like a friend, it would be Yushi. He gets along well with the other members too.
