I know, I'm late, I'm late, but I just want to pile on with 'wow, doesn't it suck when the the last chapter completely ruins the entire series?' It's not like she's gonna stop sleeping around now. Would probably be too far the other way, but I'd have liked if he had to end it this abruptly that he just had MC reject Azusa ('yeah this isn't healthy, she is in no way "just a normal girl"') and go with artist girl.
Thanks for translating at least, not your fault!
