Love is pain

Honestly, as much as I feel bad for Eunsung, he did establish that it was a business/health relationship. And Taegun accepted that. Plus, Eunsung knows that Taegun has some sort of trauma when it comes to guiding and with love/trust. So if Eunsung rlly wants to accept his feelings for Taegun and wishes to have a deeper relationship with Taegun, he's gonna have to open up to Taegun first, since he's already seen how vulnerable Taegun can be.

Taegun isn't obligated to love Eunsung back, especially since he isn't exactly in the right mental state to be in a romantic relationship rn. As of now, their relationship is similar to fwb but with more complications. But, I do hope they can open up and learn to trust each other. They can get over their trauma together
