Hello ^^
This song was performed by Back-On at the Tanabata Matsuri Concert in Sendai (08.08.2018).
I tried to search the lyrics on the internet & checked several songs of Back-On but wasn't able to find it and now I'm quite desperate.
So I would be glad if anyone could tell me the name of this song.
Thank you very much!
