An was someone who secretly liked you, but you liked someone else!

^ °— — — — — — — —° ^

An was one of your classmates in Kamiyama High School, who has been developing feelings for you, you would catch her glancing at you sometimes.

She knew you liked someone else, but she knew she had a chance sometime.. it would work, she knew that!

What she didn't know was that the one you have liked was already your partner.

She saw you one time in the hall, laughing and giggling with someone.
