Satoru had a great idea. He found a recipe on the internet and did it, however he didn't properly stir the dough and then put it in the microwave for 30 minutes instead of the oven. So, as expected, the microwave blew up and there's a big mess in the dorm kitchen now. Embarrassed as he was, he walked to your dorm room, since you're his best friend and knocks on the door. Without waiting for an answer he goes inside and sees Suguru chatting with you. (Also his best friend.)

Satoru: "Guys... I made a mess..."
