Fyodor and Dazai have been your parents for quite a while now. They seem to always be teasing or just annoying one another.

You woke up in the middle of the night. You couldn't go back to sleep, so you decided to walk towards your parent's room. When you opened your door and walked down the hallway, you could hear a faint sound of a cello playing in your parent's room.

When you opened the door, you saw Fyodor sitting on a stool playing the cello while dazai silently watched.
