That is a good point that theirs would end too, and also correct is Yiyoung is way cuter than Doyeon could ever be. He is so cute he changed a lifelong straight guy into older woman into a gay one into a younger man, starting on the night they first met, and for a few months after. Doyeon knew Kang for years and years and never made a dent, shows you how much better Yiyoung is.

More smut i to next chapter, thankfully we will see that asshole Doyeon, he tried to breakup a happy relationship sorry not sorry, and in the 4th coming chapter Kang and Yiyoung are seeing him off by his car. Kang walks away to do something and Doyeon tells Yiyoung that now that he knows that Kang can be with men, he will never give up in him. Than he tries to convince Yiyoung the relationship is doomed to fail like Kang's others, and when that happens Doyeon will come for Kang, see? Asshole. Yiyoung to his credit says "what are you an idiot? Do you really think I'll ever let someone as amazing as Kang go? , not gonna happen!" Doyeon laughs and says Yiyoung isn't so innocent as he seems, sees Kang walking back to them and forces a kiss on Yiyoung and than hops in his car and drives away before Kang can beat him up. Find someone else and stay gone!
