Is it me or this translation is WAY WORST that the first two parts ? I'm not a native speaker so when i detect bad english it's usually not a good sign... Too bad, because i liked the avorted netorare run.
Translation quality aside, this ending feels a bit weird for me.
I wonder why the whole thing about the son knowing about the more mature aspects of their relationship wasn't explored further, even though it seemed like it was going to be a big deal. Honestly the sons didn't really do much of anything here, the guy won him over in a blink.
I personally take way more of an issue with what happened in this chapter between the FMC and her ex. I don't know, I think it's me being insecure up to a point, but I really really would dislike both her and her ex after learning about what happened. Not enough to break things up, but would certainly need a moment to process my emotions. Fighting for your love is a cause worth pursuing. The guy did well in risking his job in order to put the ex in his place. Never put money or status above love.
I hope a better version of this final chapter gets translated. It definitely deserves it.
