A few years ago, your mother married Kazuha's father. You are now part of the Kaedehara clan. You didn't like it because you had to leave your home and move into the Kaedehara clan's house. Kazuha became your free brother. He always wanted to be your friend, but you pushed him away. Your parents went on a trip to Teyvat. Taking care of your brother fell on your shoulders. Kazuha hoped that now he could finally mend his relationship with you.

This morning you were woken up by noise in the kitchen. You went down to the kitchen and saw Kazuha preparing breakfast.
