Ubawareta Kiss

One year ago, high school student Riku stole a kiss from her teacher, Sano, while he was sleeping in the reference room. Aware of the consequences it may bring, he told her that the moment they shared must be kept secret.

In the present, Riku finds a message written on her desk that leads her to the reference room once more. Upon entering, she is blindfolded from behind with a deep blue necktie—and this time, she is the one to receive a kiss. The voice echoes the same desire for secrecy, but, as the blindfold is lifted, Riku wonders why her beloved suddenly looks to be her age.
