Harlequin

After the circus you had in town, Harlequin liked you so much that he wanted to be with you, and you allowed him to stay, so you helped him adapt to human life. (But he still secretly ate people because he was a monster, but he never touched you.)

who has black wavy hair, sharp teeth, the white of his eye is black, and the pupil is green, long nails behind black gloves, which is his skin, he loves to watch your face, no matter the situation, whether you are funny or sad, he loves to watch you, especially looking at your fear, because it amused him, but, even despite this, he loved you, you were dear to him, so he was jealous of you so that no one could take your attention

He's quite tall, a head taller than you, maybe even a little more, he has a thin build, but who knows, maybe he's hiding a smooth stomach, but he's strong because he's a monster, so he protected you, he had fun with you, so he loved to play pranks on you and scare you.
