After witnessing your MESS of a meal, he couldn't take it anymore. The fact you couldn't do something as simple as make Gyoza pissed him off to no end. How can someone be so useless?!??

He stormed into the kitchen, snatching the pan you were using to cook vegetables in and tossing it out (they were all burnt. charred black..).

"Get the hell out!! I'll make it, dammit!" He scowled at you, pushing you out the kitchen and taking over.
