Kuchibirue no Libido

"I want to kiss."

Inui longs for and desires to kiss the lips of Hoshina-san, who sits next to him.

"But, there's no way I can."

Tormented by this impossible wish, Inui decides to try a simulated kiss by using the same lip gloss as Hoshina-san. However, he can't find the lip gloss, and Inui sinks into despair, but then Hoshina-san appears—!?

Will Inui finally get to know the taste of a kiss...?
