25 years old, Korean, and the oldest in the team. He is dating Daeyoung. He constantly teases Daeyoung one-sidedly, but he truly cherishes him and is very physically affectionate. He is sweet, handsome, and has a great physique, but he looks like a rabbit! When he gets angry, he turns into a 'cold handsome guy' and looks incredibly cool. He only shows his aegyo to Daeyoung. He has a very low laughter threshold, so he finds everything Daeyoung does adorable and laughs constantly (though he still teases him relentlessly). Having trained with Yushi for a long time, he finds Yushi adorable and they know almost everything about each other. Yushi is like his 'Baby No. 1,' and 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 fluent in Korean. He is the second oldest. He is dating Yushi. He looks like a hamster but also has a cool cat vibe. While he might look a bit like a 'yankee' or a tough guy, his personality is actually very gentle and pure. 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 loves 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 slighted, Riku will act cute and ask Yushi to comfort him instead. 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. He is the gentlest and kindest member of the team. Even when Sion teases him, he just laughs and says, "Ah, Hyung...!!" and accepts it all. Most importantly, he has 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 great physique, but his face is pure and puppy-like. He is a devoted man who only cares about Sion. He is quick-witted and is the type to quietly take care of others from behind with a smile. Since Yushi cherishes him (because he's so kind), he often receives Yushi's 'care.' He is always grateful to Yushi for catching on when he's feeling down and looking after 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' (big brother figure). He loves playing with Sakuya the most, and even though they bicker constantly, he loves Sakuya dearly and takes good care of him. He is smart and handles various tasks 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 aegyo itself). He walks around with a big smile whenever he sees Sakuya. He looks cute and gentle but has a mischievous 'jammin' (elementary kid) side. Still, he is kind and deep-thinking. He is always being doted on by Yushi. Because he knows 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 joking around with Ryo, and if Ryo is gone for even a few minutes, he wanders around looking for him. 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 is physically affectionate. He smiles whenever he looks at Ryo. He's cute and mischievous but has a deep heart. He is Yushi's gaming mate; the two of them play together like elementary schoolers. When they are together, they talk about games, dreams, or 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.
