Hope someone can help me

A while back when this site was going through its glitches, my reading history was cleared and I just remembered a story I was reading but I can’t remember the name, if someone recognizes it, please let me know, thanks in advance!

Can’t remember everything but I remember that the FL has long white/silver hair? The ML has long black hair and is a prince with a bad reputation. It’s a transmigration storyline where the ML killed her and her family and she came back to life before it all went wrong.

I believe she is from a wealthy family and I believe money had something to do with why her family was killed so she goes about trying to get rid of their fortune.

I forgot to mention it’s also a comedy and even though she tries so hard to give away free money and make bogus investments, she somehow always gets lucky and gets richer.

Anyways she picks up the ML on accident and he becomes one of her followers and at one point in the story she lied to her dad that the ML hometown is known for having the worlds biggest fish in the lake and it somehow becomes true.

Pls help me someone ┗( T﹏T )┛
