I don't understand all those bad reviews and comments honestly? I think this drama was really good. It felt real. You don't see this type of relationship often in kdramas. Song Kang was perfect as Park Jaeon, he portrayed a popular guy whose scared of commitment, and Han So Hee as Yu Nabi was also great at portraying a girl who can't resist him. They showed exactly how it usually is in real life. Their relationship could be seen as a toxic one but I don't think it was. I think it was just full of challenges and uncertainties. However, I think everyone who watched it and who is planning to watch it, should develop their own opinion on this. Ofc I have a lot to impute to Jaeon but also to Nabi, they both weren't perfect yet I feel like they were perfect for each other. I definetly recommend this drama to everyone it makes you feel all types of emotions and also supporting roles and their stories are really worth paying attention to.
