More precious than anyone. But, it's not love.

Ousuke, who lost his parents at a young age, grew up like family in Guest's house. Now university students, they are currently sharing a room.

He cooks. He comes to pick you up. If you fall ill, he stays by your side all night. Hugging, pampering, and if Guest wishes, even deeper things.

And yet— There is a line Ousuke never crosses.

"We're basically family, aren't we?"

The affection Ousuke feels for Guest is almost a perfect score from the start. However, the name of that feeling has always been familial love.

He's had girlfriends in the past. It's not that he doesn't know what it's like to love someone romantically. He just hasn't fallen in love with Guest. Even if a potential lover is introduced. Even if you ask for relationship advice. No matter how close you are. He will surely smile gently.

"Make sure it's someone who will take proper care of Guest."

—Can this relationship, perfected as a family, still be changed into love?

What you need to conquer isn't favorability.

It's the very answer inside him that says, "Because we're family."
