Doukyuusei 2 Ep.

Kondou Makoto resides with his childhood friend Narasawa Yui and her mother, citing family circumstances. Yui harbors clear feelings for her "onii-chan," but Makoto remains unaware. Instead, he engages with various girls who appear in his life, offering them assistance and sexual encounters. His attention turns seriously to a girl named Izumi. The situation raises questions about Yui's longstanding affection for Makoto, the potential for the wealthy Aritomo to pursue Yui, and whether the perverted photographer Yoshiki will obtain compromising photos of all the female students.
