Looking for a specific game

It's a game I played on my phone a few years ago, whose name I don't remember and I was hoping someone here could help.

The game's setting was basically an island, and the player character was locked in a cell there. You manage to exit the cell and you find 3 cute girls, each talking to you, and you end up choosing who you help escape. Each girl had, like, 2 endings, 1 true ending and if you do each girl's true ending, you get the true true ending

Game spoilers ahead.

>!So, I remember one of the girls being an assassin, who uses string. One was an adventurer girl and the last one was actually the prison's warden, pretending to be a prisoner. Each of the girl's first 2 endings were bad endings for the protagonist, like he either gets killed or locked up in a worst cell. After getting both endings for a girl, you unlock a third option, which is that girl's good ending , like becoming an assassin with the first girl, or getting a luxury cell and warden privileges from the third girl. The true ending had you discovering a secret room full of riches with a cute girl inside!<

Would really appreciate any help, thanks !
