Can someone please explain the ending for me? Why did Nanami leave him? She knows how both his girlfriend and mom NTRd him and how messed up he was. But in the end she also left him? Why? He went through all the trouble of finding her,they both confessed that they loved each other and they are even had sex in front of her husband. So why did she leave him at the end? I am so pissed he had no one at the end and was back to where he started. Lately I have only been reading unhappy endings. Even though the story doesn't promise NTR the endings are always so damn bittersweet
