In my opinion, I dont think he wants a relationship but he is interested in him and likes him in that way. There is not enough of the story completed to know if he is sincere.
Again Spoilers.....A LOT of them (feel free not to click if you don't want to know up to the raws)
This is pretty much the main events that happen up to chapter 28
- During the next few chapters Param and Hwi have sex. And Hwi realizes he likes him
- Param goes out to a gay bar with a friend since the friend said that he has seen Han there before. Param gets drugged and almost assaulted
- Han saves him from the situation and kisses him before leaving him with the friend
- Param ends up at Hwi's place and they have sex again after Param is sober and they have talked some stuff out.
- At the same time Han is imagining that hes having sex with Param while hes sleeping with some other guy
- Han breaks up the other guy, saying hes "interested" in someone.
- After the kiss with Han Param avoids him, but Han corners him in the break room and tells Param he likes him and asks if he likes him too.
- Han then jerks Param off, and Param is confused/embarrassed since he thinks he liked it
- The same day Param has to work overtime and Hwi brings him food
- Hwi asks Param what he thinks of him, and Param says that he feels comfortable around him, likes how sincere he is and how he comforted him after he went to the bar. He says that he believes Hwi is a very warm person
Han is an idiot. He’s gonna lose Param to Hwi, not that he ever had Param in the beginning. Seriously, instead of playing around maybe he should chase after Param instead.
