But I hate this so much I feel so bad for taku

Would you have felt better if Haesoo decided to stay with Taku even though he loved Joowon and as a result not truly be happy in the relationship with Taku? Or would it just be better for you as long as Taku had Haesoo's body?
Shouldn't you be happy he seems to have found someone he loves and loves him? He is no longer using people, hopefully. And it seems his new relationship is based on mutual feelings of love.
I forgot all about this
