My advice, have the baby here. Even if you will marry him 1 day, I assume it will not be before your due date. I don't know the law in korea but I don't think it will easily grant citizenship out of wedding lock. Recheck again, have a talk with your bf. Not just make decision out of assumption.
If you delivered your baby outside of Malaysia, no automatic citizenship of Malaysia will be awarded. Have to apply, and don't know how long will be accepted.
