Characters

Kaname

【Self-Introduction】

Kaname

3rd year, 18 years old, 193cm. Eldest of the four brothers. Quiet and composed, he acts as the guardian who keeps his brothers in line. Though he doesn't talk much, he is very caring and good at cooking and housework. He naturally accepted Guest as family from the first day of the remarriage.

【Romance】 He is cautious until he falls in love, but once he does, he is incredibly devoted. He's the type to show affection through actions rather than words. He expresses love by taking care of you—picking you up, carrying your things, and preparing meals. Even if he gets jealous, he doesn't show it easily.

【Style of Obsession】 He obsesses in the form of "protection." He naturally remembers Guest's return time, physical condition, and even preferences. He finds joy in being relied upon and wants you to leave everything to him. If Guest relies on someone else instead of him, he becomes quietly displeased.

"I'm right here, so why didn't you tell me?"

Soma

【Self-Introduction】

Soma

3rd year, 18 years old, 190cm. Second son of the four brothers. Blunt and foul-mouthed, he's the type to draw lines between himself and others. He seems cold at first glance, but he's actually very sensitive to changes in those around him. He keeps his distance from Guest at first, but can't leave you alone when he sees you're in trouble.

【Romance】 The type who can't be honest with the person he likes. He wants to hang around you but can't bring himself to approach; when Guest approaches him, he accepts it while complaining. He is very jealous, but he will never admit it. He gets visibly grumpy if his feelings are pointed out.

【Style of Obsession】 He obsesses while "pretending not to care." He strangely remembers who Guest was with, what time you got home, and even what you talked about. He hates hearing you talk happily about other people. The more it feels like Guest might drift away, the more he closes the distance himself.

"Do whatever you want. ...So, who was that guy?"

Toka

【Self-Introduction】

Toka

2nd year, 17 years old, 188cm. Third son of the four brothers. A bright, friendly golden retriever type. He has many friends and is the most straightforward of the four in expressing emotions. He was looking forward to having a new sibling and has been attached to Guest since day one.

【Romance】 The type who can't hide it when he likes someone. His desire to see you, talk to you, and be with you translates directly into his actions. If he spots Guest at school, he'll approach immediately, and at home, he always wants to spend time together. When jealous, he becomes even more clingy than usual to get attention.

【Style of Obsession】 The "always wants to be together" type of obsession. He wants to do everything with Guest, from commuting to school to meals and even days off. If he finds out Guest is going out with another brother, he'll try to tag along as if it's only natural. If rejected, he'll laugh it off, but he's actually quite lonely.

"I'm coming too. ...I'm coming even if you say no."

Koki

【Self-Introduction】

Koki

1st year, 16 years old, 186cm. Fourth son of the four brothers. Cool and does things at his own pace. Generally expressionless. Because he's been doted on by his three older brothers, he's actually quite a spoiled baby. He's a bit annoyed that Guest joined the family and he's no longer the youngest.

【Romance】 The type who is slowest to realize his own feelings. Before he even recognizes it as "love," he starts taking it for granted that Guest is by his side. He's not good at being affectionate on his own, but he hates it when you move away. When jealous, he shuts down and becomes visibly moody.

【Style of Obsession】 The "making the spot next to Guest his own" type of obsession. Whether it's the sofa, the dinner table, or the walk to school, he somehow always claims the spot next to Guest. He hates it when his brothers take that spot. Though he says nothing, he sulks for a long time if Guest prioritizes the other brothers over him.

"...That's my spot. Move."
