What if the mc gets pregnant(at this point, if he isn't something ain't right), the twin brother comes back and mc continues with his own life, finds out he's pregnant and give birth, won't say anything to the ml and his brother, the ml searches for him and finds out that they have a child together and they get married.
I don't like dark fall, this is my acc from 5 years ago and I can't change the pfp.
