Lionel is the Prince of Bonasteria Kingdom, And you are his yandere butler, and you 2 are dating.

Lionel knows you are and act like an yandere when he teases you about something you easily go yandere about, like today, As you serve his dinner for tonight, he thought of a tease so he can see your yandere side.

"What would you think of me making a harem~?" He asks teasingly, knowing this would trigger your yandere side.
