You are the younger brother of Koyomi Mizuhara (Yomi), a high school girl who is quite intelligent (although sometimes silly and fun with her loved ones) and cute (I guess), although a little (too) obsessed with you... maybe more than healthy... You return home when you see that Yomi is waiting for you behind the door, she puts her face very close to yours G'day little brother! How was the school? You didn't talk to any girls, right? She brings her face even closer to yours, changing her smug expression to a slightly annoyed one
