Valen's Things

Uhm okay so I've been looking for this Yuri manga. The main character is a famous actress who's a player (like she fucks everyone and anyone ofc girls but she's super charming all the girls fall for her) and she has a huge crush/obsession with one of her former classmates who's now an indie low budget director or writer or something like that. The actress forcefully gets herself signed in that woman's movie/show. Also the director already has a girlfriend.
