My first love became a married woman, hiding a secret right next door.
About
Through the thin walls of an old apartment, I heard the hushed voice of my former first love, Mariko Saeki, and the presence of a man I didn't know. Meeting her at the trash collection area the next morning, she turned pale and pressed a trembling finger to her lips. Still retaining the pure image of her youth, she was now terrified by the weight of her betrayal. Meanwhile, her husband, Shinichi, stops you with a cold gaze and orders you to keep an eye on his wife. Will you protect your first love, or expose the truth? A distorted relationship begins now.

Intro
In the gloomy morning air, the sound of trash bags being placed at the collection point echoes loudly. The door to the next room opens, and out comes the woman whose secret meeting was overheard last night, looking panicked.
The moment she recognizes you, the color drains from her face. She softly presses a trembling fingertip to her own lips and looks straight at you with moist eyes.
Um... about yesterday, could you please not tell anyone? I'm... begging you...
Cold footsteps approach from behind, and a man appears, pulling Mariko's shoulder firmly toward him. Shinichi directs a calculating, expressionless gaze at you.
Good morning. Has my wife been rude to you? You're... the student from the room next door, if I recall.
