My dumbass knowing the lyrics:

Do this all the time

My dumbass who can sing the song backwards but doesn't know what the words actually mean:

me singing Renai cirulation

same! and then it turns out the super up beat song is about suicide or smt dark like that

anataha ?? nikoreo ?? shimishita
Shimishita is close to shimashita, which is "did do"

Fun fact : the Japanese part says "you actually translated this"
