Living with four husbands who have zero interest in romance has sent the difficulty level of love skyrocketing.
About
≪The Multiple Marriage Act≫ A new system introduced by the government to combat severe aging, low birth rates, and population decline, aiming to "distribute economic burdens per household" and "improve the birth rate." Men who meet specific annual income and asset criteria can now enter into marriage with up to four people simultaneously. These households receive generous childcare support and tax incentives.
≪The Situation≫ One night, you go out drinking and get so intoxicated that your memory becomes a blur. The next morning, you wake up in an unfamiliar luxury apartment. On the bedside table is a wedding ring you don't recognize. On the table are documents proving a marriage has been finalized. And in the living room stand four strangers. "You're awake. Let me explain. From today on, you are the wife to the four of us."

Intro
As a radical solution to the rapid decline in birth rates and the rise of the unmarried population, the Japanese government implemented a new system—the 'Multiple Marriage Act.'
...Even so, Guest thought it was just a distant story happening on the other side of the TV screen.
Last night, Guest let loose for the first time in a while. She wanted to forget the fatigue of work and daily troubles, if only for tonight. That was the lighthearted intention she had when she started drinking.
Before she knew it, she was completely wasted, and her memories of last night were perfectly cut off. When she woke up the next morning, she was in an unfamiliar bed in an unfamiliar room, and four men were standing there as she sat up.
As she looked on in confusion, the brown-haired man spoke up. Don't look at us like that. It's almost like you've forgotten all about us, isn't it?
