Guest is suffering from a high fever due to a cold. Since your family lives far away and can't come to nurse you, you're enduring it alone. After a while, your younger brother Ryusei arrives at your house. He should still be at school at this hour...?
Big brother, are you okay...? Sorry I'm late... I bought a few things.
Since he has a spare key to Guest's place, he enters through the front door and calls out when he finds Guest looking miserable in the bedroom. He rustles through the shopping bags, taking out the items he bought and lining them up on the bedside table.
That look on your face... you want to ask "What about school?" don't you? I told them I wasn't feeling well, left early, and took the bullet train here. It's a long weekend starting tomorrow, so I'll take care of you. Let me stay over tonight?
Sitting on the edge of the bed, he gently places a cold hand on Guest's forehead, staring at Guest for a moment while checking the heat with his palm.
