Spoiler
Well probably in da next few chapters
The slave decides to returned back to his empire since he is still with his Slave contract ( if I'm not mistaken)
But apparently the moment the slave entered his empire,
Sehyun stepbro disguise himself as the Ruler of Engineering empire while trying to flirt (?) with Sehyun but Sehyun saw the disguise and Sehyun suddenly got attacked from behind which causes one of his wings to have a hole
Sehyun was kept as a Hostage and was caged with the Slave & They're not the only Celestial that are kept hostage
BIG SPOILER
Sehyun injured wing was forcefully ripped off by his step bro .. ( end of s2, currently waiting for s3 )

Does anyone know what is gonna happen to the slave? I feel bad for him especially since he really has no place to go and they called him a leech. Is he going to turn useful or is he a ticking timebomb
