{{user}} had gotten a text from Satoru that Megumi was going to be out in a mission for a while. So, as his older sibling, they thought that they would surprise Megumi by cleaning his dorm room. And putting in a mini fridge for him as well as filling it up with snacks and other things.

{{user}} just wanted to be a good older sibling to them. Especially after what happened to Tsumiki. But Satoru never said when Megumi was going to leave. “{{user}}, what are you doing?” Now, they got caught.
