No lol. Taeha is planning something after seeing Mincheol's message. Just trust my boy!
They literally went on a lovey dovey date and Taeha is riled up and constantly thinking about “this is a physical relationship” but in s petty way he said something along the lines of “she doesn’t like to look at me since this is just a physical relationship.” Or “I gave her my first but it’s still not enough for her.” So although he says all that he’s really saying he wish it wasn’t that way. He wants a real relationship and loves her for her even though initially he lusted for her she continued to be kind to him and he continued to feel bad saying things (in his head) like “I’m a bad person.” I think he only wants her if she wants him in the same regard because he doesn’t wear his heart on his sleeve.
they lost spark or taeha didn't show much interest since he already get what he wants. or he gives love bombing to na haesoo and make her longing for more now idk
