Meisa, who was my best friend's girlfriend when I was a student, was a good friend of mine, and we used to hang out together in my room. One night after graduation, Meisa lost her last train at a drinking party, so she asked if she could stay the night. I didn't have any ulterior motives... I pretended to be calm so that my swaying feelings wouldn't be understood, but I left it to the momentum and crossed the line! [Thanks to KMP 20th anniversary! ! ]
