When i watched this for the first time i was totally on Third's side. But after rewatching it Kai couldnt really tell Third likes him cuz Third never showed him fr and never told him how he really feels.
The acting was really good.
All the crying scenes felt so real they made me be on Third side making me to Believe Kai was more than just a really shitty friend.
Support cast acting was good too.
The only thing i don't like about this drama is the ending. Where Kai Realise he likes Third. Their ending seems rushed and cuz it is rushed or it ends this way it kinda lacks chemistry.
Overall i like it a lot. Each time i watch it i cry like crazy (the way they make us believe and see the story different. That's why you should watch it at least twice to see the difference.).
