I do not care for how easily Inhwe was let off inspite of having been incredibly manipulative and endangering others (at least he had some guilt for having been indirectly responsible for Hwang-yeon getting hurt) but I'm glad everyone else got a happy ending in that timeline.
Old Seung-Tae's ending just felt incredibly bittersweet. I'm glad he could reconcile with his children, but him dying so shortly after and having lived his life full of regret feels...just unbelievably tragic.
The story for Boy to Boy/From Me to You was such a ride and MJ deserves major props for writing such a moving, multilayered tale.
The seme did a 180 out of nowhere.
