I think this is the third drama of Yoon Shi Yoon I've seen where he is typecast as the guy who gets inserted into some people's lives, falls in love with the girl, resists at first, then eventually gives in and takes the girl. This drama is even more similar to FLower Boy Next Door (FBND), in both he somehow gets involved with two people, one with Unrequited Love, tries to help them out, falls for the girl instead, takes him sometime to realize it, finally accepts it and takes the girl. For FBND, it made sense but for this drama it felt kinda forced to me and just wrong. I thought he would eventually get over his feelings and leave the girl for his son, which is the right thing to do, but when I saw the direction they were heading with the story, I felt like I could not watch it anymore. And reading the review pretty much confirms what I suspected. And where I had reached, the story seems to have stalled somehow, some characters have been pushed aside and some plot points have been pushed to the side. I liked Mal Sook's parts, especially with the grandfather and the whole time travel aspect seemed interesting but the whole show stopped being interesting when they tried to ship Hyun Jae and Woo Seung. She clearly implied she liked Ji Hoon too but was only afraid of messing up their friendship since he was all she had as a friend. So I didn't get why he was pushed to the side.
