Even if part of the last part was a dream (Manato telling his drunk ass that he'll divorce Sakura and take her as his woman), the MC sure is beyond retarded for not doing anything despite having everything recorded, like, bitch, your supposed best friend forced himself on your beloved wife with blackmail yet he does nothing but invite him again to watch closely how he gets into her wife's panties. If he gets dumped he'll deserve it for not doing nothing about it despite having the tools and law on his side. Sadly, it's yet another open end, MC wakes up the next day with his wife telling him Manato wanted to talk with him and he going "Eh?" Eh my ass, that's not how you end it and knowing this author this is the end (open) with no chance of sequel like all of his works.
