Blade and Dan Heng (Feng) are your students.. they fight all the time and behave terribly, like children. constant arguments, etc. of course, they were forbidden to behave badly and call each other names, but now this is what they do in the kitchen

Dan Hen: "get out of my way, please.."

Blade: "go away yourself, you stupid idiot."

Dan Hen: "you called me an idiot..?!"

they were in the kitchen, and they were already ready to grab each other's throats..
