My 2 cents

Okay, I'm just gonna drop my perspective on things here since so many people seem unsatisfied with the way the story is going.


DG wasn't only in love with Alex's hot body. From the beginning, it's said that he admired him so much because Alex was open and confident, traits that DG doesn't have, as he's shy and passive in his life.Yes, he only liked Jiwon's fake persona in the beginning, but he saw really dark sides of him and he still liked him. Obviously you could say it was just infatuation, but don't we all fall in love with people for weird reasons? Then, as he saw that Jiwon would never treat him right and that he really isn't the person he thought he was, he respectfully bowed out and ended things, because DG might not be the most dominant person ever, but he's not stupid either. He's loving and forgiving, but he's no one's fool and won't let himself just be used.
As for Jiwon, it's obvious why he'd fall in love with DG. DG is basically who Jiwon used to be, loving, caring, innocent, which makes him a bit naive as well. In a world with so many malicious people, DG is truly a gem (not to mention how cute he is and that they have great chemistry in bed). Honestly I wouldn't wanna let him go either.
Now, we're obviously not at the part where they know each other really well, they were just sex friends with some sparks here and there. They're not supposed to be this amazing couple YET. They still need to get to know each other, so I don't see what everyone's problem is. Jiwon is acting jealous and possessive, as he was a long time before when Md came into the picture, so it's not out of character at all.
And at the end of the day, this is just a ficitonal love story which is bound to have flaws, but can you please just enjoy the progression and them falling in love and hopefully becoming a wonderful couple, thank you. <3
