He's so cute that I'm about to lose my sense of reason...'' As I say that, my childhood friend approaches me with a face like a man I've never seen before... I, Chiaki Noto, have no luck with men and have been dumped all the time... Today, at the usual heartbreak drinking party, I was complaining to my childhood friend Yuto, I wonder if I can get married like this?'' Ah,'' and he said, I have a partner.'' Right? Right in front of me?'' He suddenly confessed to me! I was confused, but he said, If we're both single until we're 30, then let's get married.'' I thought it was just a joke, but the night my new boyfriend dumped me, he kissed me and said, I'm beyond my limits...!?'' My body melted from the melting kiss. Gradually, my body heats up, and just by touching it, my body overflows... Just like that, my childhood friend enters my insides... What will happen to our relationship...?
