Personally, I think it's sadistic to wish for Euihyun to have a miscarriage with the pretense that you want it to be so because he was raped or whatever. The only person who has a right to not want that baby to survive is Euihyun himself; not the ML and definitely not the readers.
Have you even considered how much it's going to fuck up Euihyun's mental health if he finds out he lost his pregnancy due to the stress of the kidnapping and all? Especially since he and the ML have already figured out that it wouldn't be so bad to have a baby together?
Saying he conceived the baby through rape, how sure are you about that? The time he got raped, he took birth control pills that he reacted to and ended up going to the hospital to take prescribed ones. This time, they both willingly had sex and if he is pregnant, it's not because of being raped. Euihyun willingly did not take birth control pills this time around so I assume he is ready.
Even if he isn't, it's better for him to decide to get rid of the baby himself until he is ready to have one than to have the decision ripped out his hands through a miscarriage. You think a miscarriage is a joke? Ask someone who has experienced it before. Euihyun will never forget it.
Stop wishing nonsense on characters because of your own dark, twisted sentiments. If you care for Euihyun as much as you think, you would wish for nothing more than his happiness, instead of your satisfaction.
If he ends up having a miscarriage, so be it. The author can write their story however they wish but I wish readers would stop wishing for it. It's not a pretty thing to wish on anyone.
