Is it definitely a Chinese webtoon?
It's a manhua. The top has long white hair and the bottom and black hair. They met when the top was a child and the bottom was sort of a soldier? And the the bottom thought the top was a little girl. Anddd later the house they were living in with more children was caught on fire and the bottom had to run away(i dont clearly remember it) and later the top had become some kind of top commander and they both met and thats all i remember.
