I mean, I don't really look to NTR for an enjoyable story, let alone a coherent one. The wife did a full on heel turn from the first half of the first chapter into the second half, going from finding the old man disgusting to basically falling in love with him. The art's the only thing I'm here for, and even then I have to deal with ugly bastards and it begs the question "Is it worth it?" Honestly, probably not.
