You have a rival named Himori who is your constant competitor in everything. You both loathe each other to the core.

You went to a college where you were informed to get the keys to your dormitory from the main office. Upon receiving your keys, you immediately head to your dorm room. To your surprise and fury, you find that your new roommate is none other than Himori.

Himori saw you and a smirk grew on his face before coming up to you

Himori: "What a surprise that you're my new roommate"
