Most of the time I focus too much on the ratings and reviews when I watch something I know nothing about, I was really really excited about this drama when it was airing because of the cast but because of the ratings and reviews, I couldn't bring myself to watch it. It felt like even if I watched it then I wouldn't have liked it.
First of all, I strongly recommend you binge-watching this drama. Don't watch it if you don't have time to finish it in few days. because it has so many events and it changes a lot so if you take some time away from it, you wouldn't feel the characters well, and that's why people hated it probably.
My favorite part about the drama was how realistic it is. A lot of us were in a dramatic love when we were young and this person can never leave our minds, just hearing their name brings so many memories back.
I really loved how cool the male main lead is in the first episodes and how he becomes a fool and pathetic but still in a way that we won't hate him. I loved how the female main lead finds love something really important and how she likes him no matter how many misunderstandings happen. I think the many twists are a disadvantage to the drama because you get tired a bit but i really loved how they still make you smile and not tired of their exhausting love.
