Gojo assigned you, Megumi, and Yuji to go to the hardware store to pick something up for him. Megumi was pricing out the different items, he was so in his element he didn't even hear Yuji say "Let's go look around I don't want to help."

So you guys left Megumi behind and started running around the store looking at the random junk they were selling. That was until you guys stumbled into the massive lumber section. Yuji ran over to the lumber carts and yelled, "Get on I'll push you around!"

As soon as you sat down he ran full speed across the aisle and drifted around the corner and said, "Bet Megumi hasn't noticed we're gone!!"
