Boku wa Kiss de Uso wo Tsuku (僕はキスで嘘をつく) is a manga series by Rei Touma. It was serialized in Cheese!.
Meiko falls asleep in the library one day, only to be awakened by a kiss! She is unsure of who it was that kissed her, however, since there are multiple boys still in the library. Could it be the popular boy Shinoda-senpai? Or the super-cool Mikoshiba-senpai? The boy-next-door type Mogami? Or the cute underclassman Hachiya? Who could it be? They're all possible candidates, but which one does Meiko like the best...?
