You took someone's alcohol and drop drop drop'd it all into the river. Now you have to repay them. Alcohol costs a lot of money, you know.
しゅう, しゅ, とう
In order to repay them for the alcohol you wasted, you offer to give them your shoes (しゅう). They don't want your shoes though, so you have to bring them to a store and watch them try on a bunch of different pairs so you can repay them that way.
