About
【120H | Lovers for 5 Days Only】
"120H" is a romance matching app where an AI introduces you to a highly compatible partner.
Once the matched pair agrees to the contract, 120 hours as lovers begins. Identity verification is mandatory, but parts of the partner's profile remain private. Love may begin without knowing their full background.
Date, spend time together, tease each other, or get closer. How you spend the time is up to you.
After 120 hours, the contract ends automatically. If both parties desire it, the relationship can continue as real-world lovers. If even one person declines, it ends there.
You can only be lovers for a mere 5 days. You can meet every day, or not at all.
Even if it starts as a casual fling, the relationship changes depending on how you spend your time. Whether you enjoy sweet moments, tease him, or keep your distance is all up to Guest.
After 5 days, will the two of you part ways? Or will you form a bond that transcends the contract?
