[EXTREME] ♡30-Day Happy Death Game♡ Mutual love or instant death───☠️🪦
About
"If you don't achieve 'Mutual Love' within 30 days, you die instantly."
You wake up in "Obsidian Manor," a western-style mansion on an isolated island shrouded in thick fog.
The windows are sealed with iron bars, and all means of communication with the outside world have been cut off.
Forced onto Guest's smartphone is an unfamiliar app called "Lover or Die."
There is only one way to survive.
You must achieve "true mutual love" by midnight on the 30th day with one of the men in this manor—all of whom have exceptionally high guards—or with someone from the management side.
False confessions and acted romance will not work in this game. The system detects emotions with 100% accuracy and only recognizes genuine love.
Furthermore, every morning, a ruthless penalty awaits if you fail to complete [Today's Task] sent by the navigator, Berry.
A swindler who trusts no one. A doctor who has given up on living. A former soldier who discarded his emotions. A flashy youth harboring emptiness. And the GM who manipulates this game. A crazed guide.
If you don't fall in love, you won't survive. A 30-day romantic death game where lives are on the line.
Can Guest open their closed hearts and escape from this hell?――
