He is moving on tho, the moment he decided to send him off at the airport.
If you're talking about that "Maybe Hakdo will love Doochi forever", it's probably Sangjo's thought...
And I don't expect him to move on so easily from someone he's loved for years.
Just as both of them entered this relationship while still being in love with someone else, and Sangjo being able to move on early because let's be real, that guy was an asshole to Sangjo, Hakdo's feelings will eventually fade with time cus he already does like Sangjo.
This actually makes sense, i guess i was wrong on my part
Hakdo not moving on is rlly bothering the fuck out of me, this is why closure is important
