Spicy scenes between ML and FL were sizzling hot. That being said...

I wasn't a fan of the main couple storyline.The side characters storylines were much better. Bit-Na and Nam Gyu Hyun's relationship was so cute, and had a lot of development. I'm happy they ended up together. Sol and Ji-Wan's relationship was refreshingly different for foreign dramas. My favorite relationship was the two teachers. I loved seeing their sweet relationship develop.

Lack of Character development was severely frustrating in ML/FL storyline. They should've provided some information about Jae-On's past, the storyline of Seola, and more on Na-Bi's past.

It felt like, the show-makers were trying hard to justify toxic relationship behaviour.

Na-Bi gets out of one relationship with a serial cheater, and goes right back into another. Her dismissing all kinds of red flags, even after leaving her garbage ex, is frustrating and painful to watch. She had no self respect! The fact she has to ask if he has any diseases?... because she suspects he has at least one other girlfriend, and knows he's a player, but still has sex with, and wants to be with him??‍♀️. Kissing Jae-On with another girls lipstick still on his mouth, right after he said he considered kissing the other girl "just a game" ?!
