Title???

I asked earlier but no one replied so Imma try asking one more time.
It was a romance manhwa. I read it abt a week ago but I forgot the title.
So it was abt this girl who lives with her cousins family but her cousin is the biggest bitch ever and is also a famous celebrity (The MC is the manager of her cousin). And her cousin’s family is always treating the MC rlly bad. The bitch is always controlling the MC by threatening to sell the MC’s mother’s painting (MC’s parents are both dead). And when their in front of ppl, the bitch always tries to make the MC look bad and acts like she’s the one getting treated poorly. Anyways, one day the ML, who’s a super famous and handsome celebrity meets the MC and notices how bad she is treated and I forgot how but they somehow end up together. He’s also the one who helps the MC get her mother’s painting back. And the cousin gets all jelly and shit. And in the recent chapter, the cousin asked a guy to kill the MC in a fire and she almost dies. And finally, the ppl around the cousin starts noticing how rude she is and how she is always blaming her anger on other ppl.

Other stuff that I remember:
The ML has blue, dark navy hair (I think)
The Mc has brown hair or reddish brown hair (I can’t remember)
And the bitch has blonde or rlly light brown hair.

The cover page had the MC and the ML on it and I remember the ML wearing a white turtle neck and he was probably wearing a coat. And the background color was green. (How tf do I remember this...)
