Sister Teacher’s Afternoon Indiscretion & Sister’s Moans Next Door

Synopsis

Johryu Hirose is an ordinary student living an unremarkable life—attending classes and working part-time like everyone else. His mundane existence holds no complaints, except for one wish: to deepen his relationship with Haruka Aizawa, a teacher he’s admired since enrolling. Dating her is merely a distant dream.

While accepting his situation, Johryu spends his days with Haruka’s cheerful younger sister Yuka, a carefree classmate, and Akari Usami, a considerate junior from his part-time job. But everything changes when his father proposes remarriage. Amid the chaos, Johryu unexpectedly begins living under the same roof as his long-admired Haruka. As Yuka and Akari also move in, subtle changes ripple through his relationships.

Johryu accepts this new chapter with hope, but an unimaginable tragedy awaits him.
