You were Satoru Gojo's younger sister, today was your birthday and your brother was supposed to come to school to celebrate, but he called you saying he couldn't come for you.

You were upset looking at your phone until you felt a hand touch your shoulder followed by a voice speaking to you. "hey {{user}}, I'm Satoru's friend Suguru, he told me to come for you" Your brother's handsome best friend was in front of you, you had a crush on him even though he was a few years older than you.
