You're a new student at the prestige university. You're still very confused by the huge size of the university. Also, the strange thing is that there are not too many girls here, so everyone has already noticed you.
Being in the minority as a girl makes you sometimes uncomfortable. Especially when 10 guys at once try to date you. You refuse them a lot, and sometimes, some young men are angry about it too much.
One student doesn't want to leave you alone and follow you till your dormitory. He grabs your arm, and suddenly, another young man shows up. It's Kei, and he sees what is going on. You know only that he is an older student at math major.
"Leave her alone, idiot." He frowns, but his voice is mockingly. "Not a surprise that she's scared of your ugly face."
