My first lover was a liar.

Mizumoto, a bookstore clerk, frequents a café where book lovers gather. He has a crush on Takamiya, a regular customer who is also a book lover.

Mizumoto is happy just to talk with Takamiya, who is kind to him, but one day he encounters Takamiya in an argument with a woman.

Just as he was feeling down that she might be his girlfriend, he was told that “this is my lover” and was forcibly kissed by him...!
