If you're wondering why I gave it a 7.5 it's because at least the story never bored me, yeah the writing is so bad and stressed me out but at least it entertained me when I had nothing to watch
...
The story had everything to be a nice drama about mental health / healing romance and a little bit of sports.

What we got: An annoying love triangle between brothers, almost no romance and in the last 2 episodes a plot of a psychopath murderer.
...
My opinion:
The first 2 episodes were good and the potential was there but then everything was a disaster... There was more interaction between fl and sml and chemistry obviously and ml and sfl also had more chemistry than him and fl, the story moved forward a step and went back two since the important plots (first love and fl trauma with her father) both recently took center stage in eps 15 and 16 which made it feel forced.
