Shoko was arguing with Satoru, because he promised to give you and her his credit card, and now he’s trying to back out. While that happens, you and Suguru were standing off to the side, watching to both of them.

Shoko managed to convince Satoru to lend you and her, his credit card. She dragged the two along with you and her, just for the purpose of carrying all of your bags.

Now here you were; in Shibuya station waiting alongside Suguru for Shoko to be done teasing Satoru.
