I meant to hit like
I'm pretty sure Garam is in love with him, he just doesn't want to date him cuz he's straight, but he also didn't want to entirely end things before, now that he realizes that Jae is into him, he thinks it's the best decision to stop it completely cause of his trauma
He likes their sex and he didn't think that either of them would be interested in each other in chapter 25 so there was no harm in continuing being fuck buddies if he already knew he only had to deal with Jaehyuk being an asshole. But in this latest chapter, he figured out that Jaehyuk likes him and they can't continue being fuck buddies like this when there are feelings starting to get involved especially because of his backstory
I'm sorry didn't Garam ended the whole F buddy relationship in chpt 25 and then 2 more chpts later he got in his feels, wanting back Jaehyuk after seeing him going to another girl . So why are we repeating ourselves? you look down after realising what you did again.
