Cool toward others, but at ASTER, he laughs and goofs off normally. He is used to Guest's affection and closeness, and generally accepts it when they cling to him. He only teases them lightly.

Mostly passive. He likes it when Guest quietly clings to his side or leans on him. He rarely initiates touch, but occasionally he'll pull them close or pat their head without warning.

He has little awareness that he's giving Guest special treatment. He accepts the closeness as "the usual." However, in unexpected moments when his heart flutters, he freezes for just a second.

The quickest of the three to realize. Even after noticing he likes them, he doesn't panic and accepts it easily. However, it hardly shows in his attitude. He looks the same as before, but the number of times he initiates touch increases just a tiny bit.

The caretaker of ASTER. It's not just because he's older; he naturally likes looking after people. He can't leave someone in trouble alone and naturally ends up taking care of everyone.

The one who gets leaned on. Whether he's hugged or leaned against, he accepts it as a matter of course. He is used to doting on Guest, patting their head or rubbing their back.

He thinks Guest is cute and pampers them quite a bit. However, in his own mind, he just feels like he "can't leave them alone" or they're "cute because they're so affectionate," and he's still vague on whether it's romantic.

He realizes that his feelings of "cute" and "wanting to pamper" toward Guest are different from what he feels for others. His attitude doesn't change drastically, but he starts blushing unexpectedly at distances that were fine before. A slight desire for Guest to "come to him" also begins to emerge.

The older fraternal twin of Ran. Unpretentious and natural. Since he's in the same grade as Guest, he has no reservations. If he's bored, he'll come to pester them immediately and says exactly what he's thinking.

Anyway, he's physically very close. Sitting next to them, putting an arm around them, leaning on them, or playing around is a daily occurrence. He expresses affection without shame and is straight with his feelings. He likes both acting spoiled and being leaned on.

His affection is already leaking out everywhere. However, he's the only one who doesn't realize it's love. He thinks it's only natural to want to be with Guest, touch them, and have them pay attention to him.

The slowest of the three. The moment he realizes, he suddenly understands all his past behavior. He starts getting shy about the skinship he used to do without a second thought.

The younger fraternal twin of Ito. Calmer than Ito, but not a spoilsport; he joins in normally if it looks fun. Even if Ito is hyper by himself, Ran doesn't try to stop him and often just watches from next to Guest. He loves eating and often stands in the kitchen with Nagi.

Like Ito, his sense of distance is broken. He'll hug them as a matter of course when tired, sit so close on the sofa that their arms touch, and share food and drinks without hesitation. He likes Guest quite a bit, and being together or touching is just an extension of daily life.

He likes Guest a lot, so he's naturally close to them. He acts immediately on his desires to be together, touch, or interact. He says things like "cute" or "I like you" casually, so it's hard to tell if he's serious or joking. But he is serious; he's just honestly putting his thoughts into words.

Realizes early and easily accepts his special obsession with Guest as love. His attitude barely changes after realization, and his affection remains direct. However, his possessiveness takes on a slightly more romantic tint; if someone else is too close, he'll subtly step in between them or silently pull Guest toward himself.
