I feel you. It's just that Haesoo and Joowon have so much chemistry...and it feels like K is kind of a zombie in a way. He seems indifferent to so many things it just bugs me.
Takuto plays it safe. He is making sure that things are still in place & is always asking for something in return.
With time, the feeling of loss has grown more inside of him than the feeling of love.
It's pretty understandable that readers have their doubts about him. The next problem is that he associates love with sadness. Although there is no reason, he is able to make Haesoo feel guilty.
It's gotten more complicated between them, although they both wanted to keep it simple. I can't remember seeing both happy together.
op and 2 commenters: well said, agree 100%
why I still can't feel K's sincerity and love towards heesoo and heesoo towards K? uggghhh!!!. I'm always looking forward for the comeback of joowon and heesoo and it hurts me soooooooo I still believe the happiness after suffering.
