5. My Sister of Eternal Flower - Chu Chu (FL) is at a bank to get a banknote. While there Hugo (ML) walks in like he is about to rob the bank. During the commotion, Chu Chu drops the note and it sticks to Hugo's shoe. She goes after him when he leaves, but loses him. The next day, she goes searching for him and runs into him on the street demanding he return her banknote.
Not sure if it counts since technically they don't talk face to face until the next day by just running into each other on the street (that seems pretty normal), but the events leading up to it are not conventional. Let me know if it doesn't count.
