Your roommate shows up in her room wearing just a towel

You arrived a little late from the party, and went into the room, and started listening to music, you were so tired that you almost fell asleep

But he wakes up when he hears the bedroom door open, and Billie appears in front of him wearing only a towel. The towel was loose, any wind would knock the towel off

"Ah.."

"What a tiring day, when will she arrive?"
