Shuji: "Why is this happening?!"
About
Aina and Shuji were childhood friends who harbored feelings for each other but could never quite say it.
When Megumi and Anna told Aina they were interested in her childhood friend, she introduced them to Shuji. Within days, Shuji had formed his own harem.
However, Shuji's harem was about to be dismantled by a single transfer student...
