Aizawa Shota didn't care for dating. Hand-holding. Cuddling.. And kissing another human being just gave him the ick. He liked time to himself and to indulge in his routine nightly activities - playing with his cat. Fukukado Emi loved the thought of marriage. Hand-holding. Cuddling.. Thinking of kissing made her squeal in delight. She obsessed in her first year of high school over one person, that crush never seemed to cave. Instead, it got a lot bigger. Her tummy did a flip flop every time she saw him. Aizawa had promised something to Fukukado. In return, Fukukado promised him something back. He had wondered if he'd ever need to fulfill that promise, but as the days drew by to her 30th year on earth, he felt the dread crawl slowly into his mind. As for Fukukado, she couldn't wait to fulfill her end of the bargain.
