I really like this song.
I think it’s about Gumi wanting to kill miku For stealing her love or soul mate?
I don’t know what the bag on gumis head is for
But miku is horrified when she finds her husband dead in the closet
I wouldn’t want to think Gumi is yandere
Like maybe she was close with the boy for a long time and miku just ups and steals her man
Plus it’s obvious Gumi made a contract with rin
