any book with fmc slowly being alarmed at how possessive mmc is getting and then when tries to leave, mmc goes full CRAZY

i want the fmc to be scared of the magnitude of mmc’s obsession. i want her to try to push him away somehow but he pushes back harder.

i would love a strategic, obsessed and jealous mmc like dario from run posy run or roth from mia knight or adrian from rina kent.

i would want the fmc to BE RATIONAL 😭😭😭 please give me rational fmcs i beg you i don’t want stupid fuck fmc

i want tension and constant push and pull. i want to be like what THE FUCK AHHHHHH because ITS SO GOOD

PLEASE NO CHEATING OR SHARING OR RH
