The MV content of a song in Mayday seems to be that they whispered to passers-by, and passers-by laughed.

You are not really happy, which was broadcast in May.

Tell passers-by it's Mayday guitarist, the head monster.

Tell a joke about a monster telling a joke to buy a skirt for his dying girlfriend.

Finally, people who listen to jokes change from laughing to crying, which leads to the fact that people are not happy in this society.
