Since When Were We Engaged?

"I'm going to pour my feelings into that place where you've never accepted anyone before."

Wakaba is a magazine editor who's afraid of good-looking men due to past trauma. One day, she was having a meeting with Atsushi, a hot businessman, when she angered him and he forced a kiss on her. Wakaba panicked and ran into the street, where Atsushi pushed her out of the way of a car and got hit himself. After the accident, he was acting strange. He was convinced that he and Wakaba were engaged, so she ended up living with him to care for him until his memories came back. Despite his cold attitude before the accident, he spent their days living together speaking sweet words and looking at her passionately, making her feel an almost painful love for him. "I promise to be as gentle as possible." They're only together until his memories return, but every time they touch, her heart goes wild and she ends up wanting to give herself to him.
