Unfortunately, the imbecile author named "Asakawa" completely ruined the manga "Natsu no Yari Naoshi" at the end by including NTR with the second daughter. It's a shame that he also made a bad decision by having the husband of the two daughters' mother humiliated, only to have him get cuckolded by others.
Anyway, I hope this author doesn't write any more crap stories because he really should have stayed in the end and not humiliated the husband; he should have just run away.
