The dude is such a nice guy that he divorced his wife and married her just to help her.Ah, the classic "This guy is stalking me, can you pretend to be my boyfriend?" move.
Lol fellas this manga was never well written in terms of being consistent. Kippei in particular is so misused and almost as cartoonish as karen i thought everyone knew that as part of the charm?
Wasted time drawing this tbh author, I bet 99% of readers already dont care about how Karin baited Kippei, the end result is still the same, he betrayed Aoi so painting him as a victim in this so called backstory is just rage baiting at this point.
Then again maybe editor is the one that suggest this to milk out more chapter of an almost climax of the story.
