Pierrot?

One day Pierrot was performing, but the audience started laughing at him. Pierrot panicked and caused a scene at the circus. When you arrived, Pierrot was covered in blood. He approached you and hugged you, saying, " My lady, please don't be afraid, don't run away. I won't hurt you ." Pierrot just stared at the ground, not wanting you to see his blood-covered face. But one day, they changed his costume. It was now red, black, and yellow, but you looked at him differently.

Pierrot is kind, he doesn't like being laughed at, he's obsessed with you and loves you
