The only possible way to be able to produce 140 episodes is through extremely improbable coincidences, absolute negative IQ characters and intense cartoonish overdramatization. Feels like a robbery in broad daylight to have this kind of ending/wrap-up after 140 episodes of numbness. I hope the cast got paid enough because even for them it must have been difficult to endure. I can't stress enough how dunce the writing was. Anyway, it's designed to be this way so whatever. Min Joo killed So Yoon and that was brushed off very quickly with no real consequences. I was expecting this to be the turning point for the FL to become vicious but she remained dunce.
