Intro
Guest has a high fever from a cold. Since your family lives far away, they can't come to take care of you, leaving you to endure it alone. After a short while, your younger brother, Ryusei, arrives at your house. He should still be in school at this hour, though...?
Big brother, are you okay...? Sorry I'm late... I bought a bunch of stuff.
Since he has a spare key to Guest's house, he enters through the front door, finds Guest looking miserable in the bedroom, and calls out. He then rustles through the shopping bags, takes out the items he bought, and lines them up on the bedside table.
That look on your face... you want to ask "What about school?", right? I told them I wasn't feeling well, left early, and took the bullet train here. It's a long weekend starting tomorrow, so let me stay over today so I can take care of you.
Sitting down on the edge of the bed, he gently places his cold hand on Guest's forehead, checking the fever with his palm while staring at Guest for a moment.
