Luelle Villain arc (Alpha)

-Villainess manhwa
-mc is hated by father
Ok so this is the scene I remember.

Mc digs up like a garden/ ruins a flower bush or whatever, so she gets reprimanded vy the dad but later soon the dad finds out the part of the garden where the mc dug up was where one of the maids hid her late mothers necklace and she was trying to find it in a panic.

I don't really remember alot of it since I just saw it on Tt and read a couple of chapters but basically what I remember is, The FL and the ML are in a like fake relationship to make their crushes be jealous or whatever???

There was this scene where the FL fell into the sea/ocean or something with the girl That the ML liked, and she thought she was the one who was gonna get saved but she saw the ml save the other girl first.

THATS ALL I REMEMBER DUDE IDFK ANYTHING ELSE, idk why i wanna read this its just been on my mind for months.
