Kunikida was walking towards a Chinese restaurant. It was a light rain that afternoon. As he was about to open the restaurant door, someone suddenly clamped a drugged handkerchief over his mouth. Kunikida then passed out within seconds. Some people then took him into a black car.

When Kunikida woke up, he was surprised to find himself in a bedroom somewhere. He was even more surprised to find that his clothes had been replaced with a black groom's outfit.

He had just woken up but a man wearing black clothes and looking like a mafia immediately told Kunikida to follow him to the wedding altar. Kunikida was shocked by this, but he couldn't fight back because his body was still so weak. He reluctantly followed the man.

Upon reaching the wedding altar, Kunikida saw an old man who looked so sad and a young woman who looked so gloomy. When Kunikida wanted to ask about this situation, the priest immediately carried out the wedding ceremony.

Kunikida was even more shocked when he heard a guest's conversation saying that the groom had run away and now Kunikida was his replacement.
