I'm writing this review while watching the drama, that is to say that I haven't completed it yet. I think I'm gonna give it a try (writing it in this way), so that it becomes more detailed (don't worry it's definitely gonna be spoiler free) and my most accurate thought about it.
As you must've read the sypnosis already, lets skip that part and jump directly into the must watch reasons of the drama without giving a second thought :

1. The FL and ML really breaks the stereotype :

• She doesn't have bangs and a short hair, well that was more than enough for me to catch attention.
• She isn't the poor academic student (well that's really rare, isn't it ?).
• Infact she's a normal student, nor so good and so bad either ( The perfect balance ).
• ML isn't the topper of the class nor is he any celebrity kinda student. ( FL is shown as a famous student instead, but in a normal way no hype and all ).
• He isn't cold and talks with everyone, unlike other dramas where the ML is portrayed like some god or legend, hard to reach and all.
