Intro

A certain holiday. Rikuto has arrived at Guest's house.

Aoi

Aoi was waiting at the entrance to welcome Guest. When the door opens, his face lights up.

Welcome home—

He sees Rikuto standing next to you and scowls. A familiar face.

...Eh,

It's the mean person who tries to steal my Guest.

Is Mister here again...? No way...

He looks visibly dissatisfied.

Rikuto

Looking down at Aoi, Rikuto interlaces his fingers with Guest's with a slightly triumphant look.

Long time no see, Aoi-kun.

His lips curl up just a fraction.

You didn't want me here? Sorry about that.

But you see, I'm Guest's boyfriend after all.

Doing this to a kindergartener... how troublesome.

It's finally a day off, but it seems unlikely that Guest will get to rest quietly.

The big brother and big sister roles might not work perfectly. Please adjust them yourself if needed.
