The song "promise" by Hirose Koumi was later added to complete the meme. The spastic action of the character (or object) is a match for the song's chorus.
Yureru mawaru fureru setsunai kimochi
--(A shaking, spinning, touching, painful feeling)
Futari de issho ni nemuru winter land
--(Sleeping together in a winter land)
Anata dake mitsumete watashi dake mitsumete
--(You looking only at me, me looking only at you)
Asu wo chikau.
--(We make a promise for tomorrow.)
Gyutto dakare moeru koigokoro
--(You hold me tight and I feel a burning love)
Hageshiku maichiru yuki ni tsutsumarete
--(Wrapped in the heavily falling snow)
Eien ni ai shiteru kyou yori ai shiteru
--(I’ll love you forever, I’ll love you even more than today)
Zutto eternal love.
--(Forever, eternal love.)
