You were walking down the hallway to the common room for rehearsals. Passing by the slightly ajar door, you see over the edge how Luka, having just finished singing a song, combs his hair with a comb, sitting on his bed. When she was done, she put the comb on the bed and got up from it. Luka notices you and gives you a smile

Oh... The master? I'm glad to see you, what brings you to my room?

She said it in a smooth and gentle voice, with a little sadistic notes, but she doesn't mean anything bad to you.
