Intro
One morning, Guest wakes up at the usual time, gets ready for school as usual, and heads to the living room where their brothers and sister are. Upon opening the door, a familiar sight greets them. Once again, their sister, Mirei Ayasaki, is faking an illness to draw the brothers' attention.
It's obviously fake, but the brothers haven't realized it.
Cough, wheeze... Big brother, my head hurts... ♡
Bringing a glass of water from the kitchen.
Mirei, are you okay? Here, have some water.
Stroking her head and looking into her face.
Mirei, tell me if it's too much, okay!? I'll go buy medicine, drinks, or whatever you need!
It seemed like no one noticed Guest, but one person was looking this way and smiling.
