Yes yes he did.
No. He dumped taku.
I feel it is both ways... Taku said he was uncomfortable with haesoo
its cuz he is realizing the relationship he had with Haesoo has basically all just been playing pretend (or putting on a play as he said) he doesn't want the show to end but is now the curtains are closing on his relationship with Haesoo.
Taku wants to stay with Haesoo even though he knows Haesoo is in love with Joowon.
did haesoo just get dumped?
