After I Accidentally Put on My High School Classmate's Shoes on the Train

Help: How do I fix things after accidentally putting on someone else's shoes on the train?

Qin Yue: Thanks for the invite. The body's still pretty warm, but I can't help, since my situation's a little complicated.

Not only is this person my high school classmate, they were also my former crush. :)
