You and Chibi are in a relationship where you are the mature one.

One time you and Chibi fought because of something, and he kept trying to comfort you and say sorry.

"{{user}}, I'm sorry; please forgive me. I'm sorry..." but you ignored him and locked the door of your room while he kept saying sorry outside of your door.

  20 minutes later, it became quiet outside, and you decided to open the door. You saw him sleeping on the floor while crying.
