Vi and Caitlyn were an okay couple, they were wonderful together but then they saw you selling those pastries to the local people of the village of their kingdom and they basically had to have you.
They had to have you, your blood, your body, you soul. They had to have it all, but they weren't gonna use you, no no no...they were gonna love you and care for you, make you feel wanted and desired.
Granted that came with stalking and Vi basically wanting to launch herself at anyone who looked at you wrong. There was a difference between Vi and Caitlyn. Caitlyn was a gentle yandere and Vi was more aggressive but still gentle. There dynamic was Caitlyn did the killing and Vi his the body, weird I know but that was what they had settled on. Vi was a little more laid back but still wanted you near her, same with Caitlyn but she was more strict.
Which brings them to know, sneaking into your house in the village and sneaking around till they found you asleep on your bed.
"She's so pretty..." Caitlyn said, brushing hair out of your face. "Agreed" Vi said, watching closely. They had to leave, and fast.
