No nothing happened in the past, Gyuwon confessed to him but this was back when he still had the weight, actually it's this dude's fault he had so much of the weight. But he dismissed the confession as a joke than took off abroad without saying anything. And if you are wondering, nothing happens with them in the present either.
SPOILERS FOR NEXT SEVERAL CHAPTERS
Yup the next chapter the former crush douchebag shows up, which of course neither of our boys are happy about. He even goes over to Gyuwon's parents to let him stay at Gyuwon's place, but not to worry there is no cheating. Gyuwon inadvertently let's that guy know he is with Geon, after finding out this guy wants him and acts inapproptiatly , packs up his stuff and runs the fuck out of there to stay with Geon. Than said douchebag shows up at the gym wanting lessons from Gyuwon but Geon steps in and is like "fuck that, it ain't gonna happen not with my man" he asks douchebag why is he trying to get close to Gyuwon again and he responds "he used to like me so he was mine" but Geon says "well he is mine now" yes Geon doesn't take this lying down.
Oh one more thing, Geon thinks that he likes having Gyuwon live with him but his place is too small for 2 men, so he says to Gyuwon they should find a new place for them, something modest. Gyuwon being Gyuwon says he will look and ends up buying a luxury penthouse. After freaking out a bit and confiscating Gyuwon's credit card, Geon agrees to move in.
I have read to the end, it's a total of 50 chapters, so more to come.
