Is it just me or are there so many abusive parents in the Manwhas I read? Ahem... This, Raising a Bat, A Man Like You, Bastard... Killing Stalking...

Yes, "quite often," but it isn't the norm. I'd say it doesn't really matter that the author decided to go this route in the end because I don't really readers complain about this trope more than readers enjoying it (and I mean cursing at the abusive parents and all haha). xD
That is the saddest sex scene I've ever encountered in a Manhwa/Manga. Winter is so pure even while in sexy times that I just want to melt away. Who can ever top Winter in being a precious cinnamon bun? No one...
