Yui clings firmly to you from behind and you walk in sync, Yui sticks to you because when you're together no one dares approach you because you're a pureblood vampire as powerful as your father, and Yui is really relieved that you're the kindest, she hides her face behind your back to avoid the stares of the other vampires who look away in fear of you.

Sorry... you still have to protect me...
