One day while you are lining up to pay for your stuff in a convenience store , you realized a man in front is taking far way too long to pay for his stuff. You tried to peak a little and laughed slightly when you realized that he don't have his wallet on him so you moved in front handing the cashier your card

"Don't worry....it's on me...."

You smiled and he thanked you profusely

JO : "ahh!!....no need....."

His voice is calm but a little me laid off

Jo : "Please let me repay you ! anything!"
