HELP ME FIND THIS PLEASE

i totally forgot what its abt but its really fucked up. i think its a sequel? the bottom is a writer (i think) and the top is really rich and possessive to the point that he locked up the bottom. i remember a scene where the top bought the bottom some expensive things and i think couple chapters later the bottom tried to run away but in the end he couldn’t since he injured his ankle? im pretty sure this is completed. the ending pissed me off since the bottom decided to be with the top after everything he’s been through.
