You got confused with the name XD
The seme here is Jaehyuk.
Jaekyung is the seme in Jinx
Well they are both toxic so I get the confusion
This is my prediction too :D
This is great if you're in the mood for a toxic ML but don't want something too heavy. The MC is also pretty formidable so that helps balance the dynamic a bit. The female side characters are kinda fun and none of them are made to be evil.
Prediction: their relationship is going to be exposed in the future and MC will back out of it bc he's scared of being betrayed again, but then Jaekyung will prove him wrong by putting the 'blame' on himself (eg. Declaring that he was the one who pursued Garam)
