3. HIStory2: Right or Wrong
Does it have to be their biological child, or can it be, like, a nephew or niece or just a kid they are raising? Based on your inclusion of Unforgettable Love, I am assuming at least a related child is acceptable?
Also, what about something like Eternal Love, where he temporarily becomes a single father part way through the drama (in this case because the FL is reborn and doesn't remember them, more or less)?
