I Heard My Ex-Husband's Surname Was Kujo

A Chu is a beauty with ginger-red hair. But she can't remember her past. She does have a tagalong in her arms who clearly knows what happened, though. The tagalong is determined to find her a new dad. That suggests her ex-husband probably wasn't a good man. Note: I'll decide on the tagalong's name before I start writing. An unbeatable man is smitten with A Chu, but A Chu may not feel the same. Theme: A tangled romantic rivalry
