Ryoudonari no Hitozuma ~Sou Natta Wake wa Apart no Kabe ga Usukatta kara~

It wasn't long after I moved into my apartment that I started noticing the conversations and noises coming from next door. Both of my next-door neighbors are married men with beautiful wives, albeit of different types. Hearing those voices every night brings me great agony, but as I listened to their conversations, I realize that each of them seems to have their own problems. Would it be possible to get close to them in order to solve their problems? With that in mind, I immediately set out to find a solution!
