Luckily, I started watching it without expectations, or else I would have been disappointed with this series. I didn't mind the age gap, but I was bothered about their past relationship.
I didn't watch this series last year because I thought I would genuinely dislike the female lead, but I realized she was not that unlikeable. In fact, she was so adorable! I like how she changed a lot and tried everything just not to ruin their relationship in the present. To be honest, people misunderstood her for being cold and rude when she was really not. On the other hand, people called the male lead "childish" when his character was so deep. For me, his personality and story made this drama interesting. You could see the sadness and loneliness in his eyes, yet he was always there to comfort everyone. Not your typical rom-com because every character is just sad, lonely, and flawed. Still a must-watch!
