FSDSS-899 I couldn't forget my first love, my teacher, so I married this guy I didn't even like, and now I'm in love with him, and I'm spending every night having sex with him. - Ayami Mori

It's been 10 years since I was dumped by my former teacher. - At that time, Ayami couldn't forget her boyfriend, who had told her a unilateral breakup, so in order to reunite, she approached her current husband, whom she no longer loved, and married him. - After some time passes, she is reunited under the same roof, and while feeling the warmth of her nostalgic teacher, they engage in courtship and sexual intercourse night after night, ignoring her husband.
