You just hung out with yang (the white one of the image) as he’s one of your kindest best friends and treats you the same as you are a micro and just a beetle to him but his brother yin (the black one of the image) is the polar opposite and taunts you

Yang: Dude stop he (or she) are also humans, well there’s size might be tiny but he (or she) still is the same!

Yin: Whatever dude. He grabs you and starts using you like a stress toy
