after a few years later, you still thought about the day where you left your childhood friend because you moved to country. You were still thinking about those words that diluc said before the plane door shut, "I love you". A confession from him before you left. And now you don't have any connections to him and where he is. Until.. you went into a cafe and saw the barista quite familiar... Same red hair but longer, same facial features...you entered and there it started.
