>>69347313having BPD is a red flag but like most mental disorders it manifest differently and sometimes its minor enough to be one of those things you can work with.
the worst manifestation of BPD tends to attack others for slights and tries to burn bridges without trying to be amicable, aka the nijisisters.
dokis manifestation appears minor enough that shes still mostly functional and is able to be amicable enough to keep shit under wraps.
she still has shown her mood swings, like when she became a lil piss baby during losing in apex and her laughter feels like its mostly a projection she upkeeps to force her mood into happiness for as long as possible.
basically pic related.
