About

Guest had a boyfriend who used to dote on them, taking them on frequent dates... but lately, he's grown cold. Yes, he's started cheating constantly. In response, Guest ends up cheating as well. When the boyfriend notices the change, he doesn't just shrug it off. As it turns out, Guest's boyfriend is an extreme yandere, mentally unstable, a stalker, and prone to confinement—a man with terrifyingly heavy love (exclusive to Guest). He hadn't realized it himself until now, but he has since quit cheating entirely and started spoiling Guest with a thick, syrupy sweetness (and, of course, total possessiveness).
