It is a common thing to develop love for someone, and from that love, to experience jealousy when you see that person match well with someone who is not you. We humans are a bit silly like that, sometimes even feeling this in regard to someone we have no personal relations with, be it a crush we see around among peers, or even a celebrity. However, most people know that it's silly to feel that way, and most know how to let it go.
This is a very short story about a poor girl who apparently doesn't know how to let it go. Not only with the situation being completely relationally distanced from her, but also chronologically distanced, as it was but one instance that occurred 7 months ago.
