During his childhood days, Tsurugi and Kiyou were best friends. Kiyou had love feelings for Tsuguri but after realising this, Kiyou tried so hard to act normal, until one day he ended calling Tsuguri "gross" without knowing that they'll not be able to see again. Years after, during the las days of high-school, Tsuguri appears in front of Kiyou and all those feelings that he desperately tried to suppress are now on the surface once again.
Their feelings were the same and all but, really? Out of desperation, Tsuguri just raped his friend. Man!
