I didn't like it but I didn't hate it that much either. Taesoo was an asshole and so is Shinwoo and they really needed that closure although why does it have to involve cheating?? It was confusing for me at first but when I think about relationships nowadays, I thought to myself that things like this may happen in real life. Sometimes we hold on to people because of regret and mistake it for love, just like Shinwoo. Although I don't tolerate cheating, I think some mistakes are needed to happen in order for Shinwoo to realize his true feelings and I AM BEYOND FCKING GLAD HE DID SNAP OUT OF IT! Sebin you poor idiot but I'm glad you are happy and working it out with Shinwoo.
