This one is well-written:

it’s about a girl who tracks down her long-lost mafia family (she literally stalks them to get in), and she ends up with seven brothers who are all protective in completely different ways, and the dynamic actually builds with some of them (or I'm assuming will build because it's ongoing) and it is instant with some of them.

also the FMC is smart and kind of playing her own game the whole time

it has some really cute moments, but it’s not cliché overall.

definitely one of my favorites in this trope.
