Three Days of Happiness is a novel by Sugaru Miaki, also known as Fafoo. It’s a rewritten version of the story originally posted to 2ch.

The premise of the story revolves around a shop where one can sell away the remaining years of their life, and the consequences of doing so.

“I Say A Little Prayer” is a short related story which was posted along with the novel’s release. It spoils some things about the main story, but nothing major.

I reincarnated as Luna, a supporting character who is accused of ruining the heroine and hero’s relationship, and is mu*dered. I’m not interested in someone else’s man, but the heroine’s friends bully me every day. “Why are you trying to get close to someone who’s already taken?” “That’s right, please stop! Why are you doing this?” “Stop doing such terrible things!” So Luna decides to announce it in front of everyone. “I don’t want someone like Fersen even if you beg me to take him so stop bothering me. I’d rather date Anthes Vincent, who’s rumored to be insane.” And soon she meets someone who she never expected to meet…… “I heard you have an interest in me? The truth is, I do too. Is it a coincidence?”

They are childhood sweethearts, they are engaged under the family’s scheme, and they have to live in the same room and sleep together.

That night, she was accidentally drunk, and he kissed her in a fascinating mood,. By accident, his “crime” was finally discovered, she accused him, but he said with a smile, “You are my wife, why can’t I kiss you?”

The two people’s daily routine is full of bickering, mutual hate.

He said that he disliked her. Actually, In his heart, he was extremely caring of her. When she was close to other boys, he was so jealous that he wants to tie her to his side and become exclusively his.
