[Tanboku Shiiku.] The last night of an ordinary couple

An ordinary couple—wife Saki and her husband, with their two kids in tow—seemingly settles into a quiet evening at home, trading small talk about groceries and a manga recommendation. But the domestic calm shatters when a stranger invades their bedroom, pinning Saki down as she tearfully gasps "I ran away... please!" and violently claims her while her horrified husband watches from the doorway. The aftermath reveals the violated wife disheveled and the predator triumphantly declaring "This is my first time. I felt like I was living life seriously. I'm so excited about my release! I can't wait to meet my lady!", promising this is only the beginning of his obsession.
