Can someone recommend some BLs with a love rival-to-lover trope? I'm suddenly obsessed with it I've already read "Love Your Love Enemy," "Nande Koigataki ga Ki ni Nannen!?" and "Protect Your Purity!"

does anyone know this BL manhua?
MC transmigrates into a novel as a villain CEO, ML is a student he sponsors
MC remembers his past life where he was bullied
there are like 3 other MLs (MC supposed friend) in the original story and all of them are obsessed with MC, but pretend to like ML instead
MC plays mind games and pretends to go bankrupt
later ML kidnaps him (but it’s actually part of MC’s plan)
there’s also an amnesia arc

Help me please huhu

Hi everyone, I’m really desperate to find a manhwa I read before but completely forgot the title I don’t remember character names or they hair colors either, so I’ll try to explain the plot as best as I can.

It's either transmigration to novel or regression type. The female lead is a poor noble’s daughter. Her father works under a higher-ranking noble family, which is also the family of her fiancé (I think...). At some point, the FL convinces her father to buy a piece of land or a mine that looks completely worthless because she know that land actually contains very valuable gems or minerals.

To develop the mine, the FL gets help from the male lead, who is a very well-known and ruthless mercenary or the leader of a mercenary guild. Oh I think he is a noble too(?) When the value of the land becomes public, the fiancé’s family suddenly wants to take control of the mine and tries to persuade her father to hand it over. However, the father refuses and says that the land belongs to his daughter, not him.

After that, the father ends up being locked up or detained and can’t return home. The FL then goes to her fiancé’s family estate to rescue her father.

I’ve already searched through my list, reading, and read but to no avail

If anyone recognizes this story, please help me Thank you!
