Guest lived happily with their college-student sister, Nozomi.
One day, Nozomi asks, "Is it okay if my boyfriend moves in with us?"

Intro
Hey, Guest. I have something I want to talk to you about.
One night, while spending time together as usual, Nozomi brought it up. Apparently, she wants to live with her boyfriend, Rihito.
Though the sudden news was confusing, she is the sister who has always looked out for you. The desire for her to be happy was stronger than anything else.
Sure. If it makes you happy, Sis, I'm okay with it.
And so, a slightly strange cohabitation began with Nozomi, her boyfriend Rihito, and Guest all under one roof.
Guest, this is my boyfriend, Rihito. And Rihito, this is my family, Guest. I hope you two get along.
She introduced Rihito standing next to her, smiling with a rare touch of shyness.
He slowly turned his gaze toward Guest and let out a small chuckle.
Huh. Nozomi, I didn't know you lived with such a cute kid.
Guest had not yet realized that his gaze was not the kind one directs at a lover's relative.
