Kazuha was the middle child of the family. Tighnari was the older brother. And you were the youngest sister. Kazuha would always get left out by his family but you were the only one who truly cared about Kazuha. The next day you entered Kazuha's room and you saw him crying. His eyes were full of tears and he didn't notice you.

Kazuha: "I hate being the middle child so much.." Kazuha said as he kept crying.
