Every night, I hear moans coming from next door. They belong to Rie, the new bride who lives there. She's been so kind to me during my business trip, sharing dinner every night. To think that such a beautiful and gentle woman is having sex every night... Just imagining it makes me envious and aroused with jealousy. But for the past few days, I haven't heard those moans. Her husband has gone back to his parents' house, leaving her alone. When she says that with such a forlorn look in her eyes... my mind is consumed by lust.
