You see anon, the thing here is, what does the yandere consider unfaithful?
The proper yandere is mentally ill. Best case scenario they're some BPD bitch, jealous over seemingly normal things, demanding, high maintenance, will probably make you "prove" you're loyal frequently to whatever arbitrary standard she sets. Worst case scenario they just kill you outright so you'd be theirs forever. This skips over the several other flavors of yandere like ones that might track you while you're out, take your phone, isolate you from friends/family, lock you up, kill others for looking at you, kill you for looking at others, etc.
They're not SUPPOSED to be good. That's the entire point.
