It was in a school, the vocaloids singing are: Kagamine Rin, Megurine Luka and Hatsune MIku, it was an animated video and they wore school uniforms, normal and sports uniforms; it was a cheerful song -or at least it sounded cheerful- i can only remember some lyrics, obviously misheard "happy kokoro no nai te ... amai dame dame" "ichi ni san" "kyun kyun" "mirai kimi ki nai" "matte ... kawaii kokoro no" "motto daisuki ..." i tried searching for the lyrics but there's nothing and i remember reading in the credits of the video something about "pea soft" but google only brings me pea recipes or how to take care of peas in a garden... and youtube brings me stuff about the soft append and this song was in youtube before the appends. Thank you in advance!
