Issue addressed by main FL herself that she did cheat on JW and HS is something to ignore? Like cheating seems normal in drama JW & HS school ex also cheated on them ...then again fl also hurted JW and they still wanted to hold into her....was that actually okayy?? Like for a "kdrama" it's okayy dramas like Marry my husband can be example when it's reverse point of view where boyfriend and her frd cheats....here from JW(2nd leads) Pov his girlfriend and frd cheated. So why one is being justified just bcoz they are leads in this my and other were just villians (antagonist). 

Turning blind on this would actually make the show better/ funny for me. But i just can't? Everyone enjoyed the drama like this anyways.
