- Author's comment

"Check Check Check One Two!" is an original song by KurageP and is one of his most notable songs. This song can be viewed as the spiritual successor to "Chururira Chururira Daddadda!" in terms of style.

The song concerns a 17-year old high school girl who spends her first love obsessed with her teacher. In her spare time, she secretly records his voice and splices the sound bits to make confession tracks for her own listening pleasure. When she spots another student interacting with her teacher more, in a jealous fit of rage, she plays one of the tracks over the school intercom, just so that she could assert possession over her perceived rival.

This song has entered the Hall of Legend, and has reached over 4 million views on Youtube. It is featured on the album Diary of Underage Observation, where it has a short manga adaptation that came with the limited edition version of the album.
