In the raw jin warned chiwoo that hwan is dangerous,and then hwan got jealous over jin then he started fcking(more like raping ig) BLAH BLAH I'm to lazy to type xD
I think after jae-woo acting like sae-woo(?) i think he will developed some feelings more and more and he will not tell his twin brother that he has feelings for him D:, and it makes them both harder or the will fight something like that :{,(this is just my opinion not the actual one xD)
JEBUS I DONT KNOW ANYMORE MANN I FEEL LIKE THE STORY WILL BE BETTER IF JOOIN IS SINGLEE
