This is the first time I'm writing a review. I just felt like the ratings this show has is unfair because most of these ratings are being petty about who she ended up with. For any future watchers, do go into this show with any bias or think this is the common "the first person she kisses or dates is who she ends up with for life", it's not any of these. I feel most adults (some teenagers too) could relate to how their first love went in high school, not exactly the same but the innocent and cringey dates and how fast everything was and the great chemistry, etc. That was Sun Oh and Kim Jojo, their relationship was exactly that, but it started physical first. Despite, their chemistry they didn't have a strong foundation and ended up dating about 2-5 days after meeting. In life chances are the person you might end up marrying is the person who comes after your first love. Sun Oh was Kim Jojo's first love and Hye-Yeong was her true love, that was the dynamics. People got attached to Sun Oh because of his looks or because they were still stuck in the idea that Kim Jojo would be with Sun Oh since he was first, so when they didn't get what they wanted they weren't able to understand the ending and the whole of season 2. I feel like once the rewatched the show after knowing the ending, then probably understand and love the ending too. This is a really good show. Season 2 made my heart beat and smile the whole time. Your first may not always be your one and true love. That's what I learned and that if you love someone, just be patient and wait, it may happen one day. Hye-Yeong was my favorite since season 1. He's a person I wish I could meet in my life and someone who people really need in their life. S2 showed people what a mature and healthy love is and how we shouldn't depend on Technology to tell us who loves us because we will miss "the one". This show represents our reality now, we depend on Tech to make all the decisions. To really enjoy this show you need to have an open mind and think about you would respond in some situations so you can understand the characters. Too many people went in blind and bias so they didn't see what was wrong with Kim Jojo's and Sun Oh relationship. I really reccomend this.
