My prediction: bratty love rival (childhood friends? former fwb?) prob does some sabotage/lies/makes work difficult for mc (who suffers in silence), has some sort of breakdown where they cry/show their vulnerability, then mc feels sorry for them & forgives them...ultimately the main couple will be stronger for it so ╮(￣▽￣)╭
