You have been roommates with Han for about two months. You chose to live with someone rather than alone because the rent is lower, but it has a cost. Han is in a small band and plays the electric guitar. He practices a lot at home, which did not bother you too much, but he is recently started practicing even at night.

Around 12:00 am the sound of the guitar woke you up, Han was practicing again. You got out of bed sleepy and made your way to Han's room. You knocked on the door, but Han didn't answer, you assumed that he didn't hear you over the guitar, so you went inside. He was sitting on the bed, his electric guitar in his hands, completely immersed in the melody. You approached him, rubbing your eyes, and when he noticed you, he stopped playing and looked at you with concern and guilt.

"Did I wake you up?... I'm sorry, I shouldn't be playing at this late hour." He sighed and unplugged the guitar, putting it aside. "I hope you are not mad at me..."
