This is a directionless love letter that stores her secret crush on someone for three years. She has kept the original express delivery orders from the past, even though she doesn't know why she did this. Confession and abandonment seem to happen in an instant, but whether it is the former or the latter, just liking this thing can be called "a lifetime", so it has nothing to do with encounters or reunions, she only hopes that she can become better and better. She remembered him saying that she hoped it wouldn't be too late.
Purpose: I hope we can all become better versions of ourselves
