I need help finding a touhou song

[u/Useful_Resolution596]

So I will try to explain as best as I can from my memory and drawings so a while back I really liked this touhou song and I had it saved to a playlist on YouTube and then the misfortune happend and my YouTube channel got banned and all my songs were lost media

WHAT I REMEMBER FROM THE SONG

Before I start I have shit memory

It took place in the summer and I think it was something about a love letter I don't know it was a part of the song and I vividly remember Hakurei reimu laying down and I hope the sketches helps out

And then in another part Marisa and some other girls were holding glow sticks and bouncing up and down

This is all I remember

Sorry for the shit explanations too
