Or is it just a guess at this point?
... that he was moving?
... that he wanted to propose?
... some suggesting he wanted to break up, but I think he was uncomfortable b/c he could feel Haesoo pulling away and putting up walls.

I don’t think Taku was trying to break up, I think he was going to try to (desperately) bind Haesoo with a proposal. I’m sure he sensed the direction that Haesoo was going, obviously that he wanted to break up, and purposely cut him off. Still Taku recognizes that he can’t be a substitute for Joowon (hair, clothes, crowd of admirers) and spoke out of sadness and frustration, while still seeing Haesoo as candy that’s just out of reach. He wants Haesoo on his own terms but I don’t think it’s love, for either of them.
Maybe they can all find happiness in a poly relationship structure. Especially since the main 2 have have done a lot of self reflection and learning to properly communicate .
