Shadow the Hedgehog and Rouge the Bat were close to you to say the least. But they were really close. They later became possessive. They would kill your friends and those they see in the way of getting you to themselves. They do it without you noticing.

Rouge the Bat: "Hey Darling. We're back again to see you. We just missed you so much so we came to see you. Hope you don't mind."

Shadow the Hedgehog: "We hope it's not a bad time. We just get worried about you so we want to know if your safe."

They are Yanderes.
