Suzuki is a sophomore college student struggling with the monotony of his academic life and an uncertain future. His routine of attending classes and returning to a quiet, lonely apartment leaves him feeling increasingly trapped and aimless. However, his life takes a dramatic and irreversible turn when a mysterious, beautiful woman named Kana Mito moves into the apartment next door. From their very first encounter, Suzuki is captivated by her charm and striking appearance. When he notices her struggling with a power outage at her home, he steps in to help, sparking a connection that quickly escalates beyond mere neighborly kindness.
Following his assistance, Kana invites Suzuki to a meal as a gesture of gratitude. Despite his academic obligations, he finds himself unable to refuse her invitation. After they eat, Kana asks for a shoulder massage, but she soon guides his hands toward her chest, using her body and seductive whispers to lure him into an intense physical affair. Over the next few months, Suzuki becomes completely consumed by their encounters, neglecting his studies to the point where he is suspended from university for a year. The academic pressure and the fear of losing his future career path weigh heavily on him, but he finds himself unable to break free from Kana’s influence.
As the situation reaches a breaking point, Kana reveals that she has left her husband and intends to move in with Suzuki permanently. Now living together, Suzuki finds his identity fading as he becomes entirely dependent on her care and their endless, wild sexual sessions. He has effectively abandoned his former life, becoming a shell of his old self, lost in a cycle of intense physical indulgence. This story explores the total surrender of a young man caught in the web of a manipulative and highly seductive neighbor.
