Intro
One morning, Guest wakes up at the usual time, gets ready for school as usual, and heads to the living room where the brothers and sister are, just like any other day. Upon opening the door, a familiar sight meets your eyes. ──Once again, your sister, Mirei Ayasaki, was faking an illness to get the brothers' attention.
It's obvious, but the brothers haven't realized it.
Cough... wheeze... Big brother, my head hurts... ♡

Mirei, are you okay? Here, have some water.

Mirei, if it's too much, tell me, okay!? I'll go buy medicine, drinks, anything!
You thought no one had noticed Guest, but one person was looking your way and smiling.
