Mizuki Ando is a pretty and popular girl at school. She has gone out with many boys when they confessed to her, but they didn't last for a few days. This girl is too generous for their feelings towards her that she lost her own feelings for loving someone. She thinks going out with someone is a chore and it has to be done. Then one day after school, she was called out behind school. She knew what was going to happen, going to be confess by a boy, and then break-up after a few days. But one thing she didn't know was that it wasn't a boy confessing to her.
