This is absolutely bullshit.
I read the first chapter a few days ago, and ... I drop it right away.
If you belong to those lines that says "This is interesting because it's different", but for me it's more like if you're the type who likes and wants to accept cringe love like Kuzu no Honkai, Koi to Uso, etc ... very welcome.
I can't stop laughing because I'm annoyed with the male lead and his "It's different when I meet this married woman next to my door." mindset. There is something wrong with him. Most likely the heroine will surrender and follow her boyfriend's demands? Or the bad is not going to know in the near future, behave like the best girl, and ---hopefully, there will be a new character who will take her from a man who doesn't want to appreciate her enough just because "she didn't have sex with me at the time."
