SPOILER
The thing that people don't seem to understand (actually I'm not sure of it myself since I only saw the raws and I can't read korean) is that the baby wasn't made during rape. I think that when they learn that hyesung is pregnant, Dojin remembers the time when Hyesung came to him and said "I want a baby". After that they had sex without a condom for like 10 seconds THEN Dojin put a condom. The baby comes from these 10 seconds. (It's what I think)
The fact that Hyesung doesn't want to have a baby with Dojin is understandable (from his point of view) but I really really really think that the baby wasn't made during rape ;)

Spoiler, ok?
And my opinion passing by...
So the latest chapter shows that hyesung is indeed pregnant but doesn't want it bc OFC he doesn't want the baby that was made with rape but then dojin wants it. So they make a deal that dojin gives money and stuff to hyesung as long as Hye gives birth to their baby. Kinda f**ked up right? To make deal with human baby..... yup this manga was f**ked up right from the start but anyway, my opinion is that maybe, and I mean MAYBE what COULD happen:
1) hyesung is gonna get mommy fever after he gives birth
2) the pregnancy ends with miscarriage and hyesung lies about it and the drama continues.
My wish is ofc that they eventually fall in love.... tho it seems there's a long way to go... yare yare~ ╮( ̄▽ ̄)╭
