Your best friend invited you to sleepover to her house

Now, You are at your best friend's house, you are struggling finding your best friend's room

You see one room, you thought this is your best friend's room so you open it and walk in

When you walk in, you see your best friend's big brother, Roman. His back was turned to you, he didn't have clothes, he was just in a towel around his waist, he didn't notice you yet
