Congratulations on your graduation, it's been five years just like back then… My son's friend, Kitayama-kun, and I have continued our friends-with-benefits relationship for five years now. It all started five years ago when my husband's infidelity was exposed; Kitayama-kun comforted me with a gentle kiss as I was devastated. Not wanting to interfere with his exams, I waited until the day of his graduation ceremony before finally responding to his feelings and having our first physical encounter. For the past five years, we've been sneaking around behind my husband's and son's backs, but things started to change when Kitayama-kun got a girlfriend…
