どうでもいいや (Dou de mo Ii ya)

Background
The song is about Len who is trying his best, but always messes up and leaves others disappointed. He ends up doing things halfheartedly and thinks "Whatever," or that he doesn't care whenever someone criticizes him. Len accepts who is actually being bad. He realizes that it's not alright for everything to have no meaning; he is not useless. In the end, Len just goes to sleep and "to be continued" appears on the screen.

Oichan-P has stated that the "to be continued" at the end of the video means that it continues the next day.

Trivia

 * Like most of his other songs, Kuma the Bear is present.
 * Oichan makes several references in this song as well. In the beginning you can see Winnie-the-Pooh and later on Len dressed as Luigi while getting a 1-UP.
