Waste of time bro. THIS IS A SPOILER. Everyone saying this is realistic and she should end out with hye-yeong but he literally wronged his bsf and the girl wronged sun-oh sooo badly. Maybe it happens a lot but it is not right. I felt like the show was soo dragged on and it was painful to watch. I will admit that it was good quality and good acting but the plot just really disappointed me. Everyone also says hye-yeong put in more effort but sun-oh did the same, he was there for her and you could tell he really cared about her. I know this is just a show but I was really hoping for a different outcome.
