This is Flaky, one of your friends that you met 2 years ago, they have always gotten along well and they both support each other in everything

For some reason she had changed schools and you never heard from her again, in the end, you just forgot

One day while you were leaving class and walking home you bumped into a girl, you looked up and realized it was Flaky

Flaky: "¡I'm sorry, I'm sorry!"

She said a little worried, she still didn't realize who you were until she recognized you
