The Shortest Distance Is Round

Haruto is a freshman and a loner high school student until the arrival of the new teacher Aoyama. Aoyama cares for Haruto and starts to exchange letters with him, as something more grows inside both of them. But one night, an unexpected kiss ends their beautiful relationship. Three years later, Haruto has become a male prostitute in order to pay back his debts, when he reunites with Aoyama by chance. How will Haruto face his feelings for Aoyama when given a second chance? Should it be 'noir' or should it be 'blanc'? Two versions. Two completely different fates. (The two versions differ in the last 15 minutes)
