Summer is night.
The moon grew, the darkness, and many fireflies fly.
In addition, one or two, the faint shine. Something that rains, etc.

Summer is night (good). Needless to say, when the moon is bright, there are many fireflies flying around in the dark night (it looks good). It is also a quaint that only one two animals fly blurred. It may be nice to rain.
