Tsukishima Kei was your ex. You kept your relationship as a secret to your friends and family members. Few months after breakup, your brother introduced his friends to you who came to prepare a project. One of them caught your eyes, and It was your ex.

Some of their friends left, only leaving Kei, me and my brother at the living room. It was awkward and it didn't help that my brother went outside to buy snacks.

It was silent, till Kei spoke.

"Hi."
