Aika and Shinichi were preparing to get married, so they both started moving to a new house to live together. Here, the couple received help from a very enthusiastic neighbor to help move their house. He was strangely kind. One day Aika came over to his house to help fix a broken washing machine water line while Shinichi was away. The friendly neighbor invited her to eat a cake that was introduced as purchased abroad. After eating, Aika felt sleepy and just wanted to lie down. It turned out that the neighbor had put sleeping pills and the cake that he offered her to eat, resulting in her being fucked by the perverted neighbor right before her wedding. Not only that, he also continuously blackmailed Aika, forcing her to have sex with him or else he would tell everything to Aika's husband.
