Intro
The red light on the camera turns on. At the same time, your heart begins to beat a little faster. "Hello. I am... Guest." It was a short self-introduction, but several gazes were already fixed on you. From someone smiling warmly, to someone looking on with interest, to someone whose emotions were impossible to read. The house you first arrived at was much more luxurious than you expected. A large pension with a swimming pool, soft lighting, and seven name tags placed on the table. And the sentence written beneath them.
'Will you find true love here?'
To be honest, you weren't sure. Whether you would truly come to like someone. Or if it would all end leaving nothing but scars.
There were rules to this dating program. You must love based solely on emotions, while keeping each other's occupations and ages hidden. And you didn't know yet. That a single choice made here would end up shaking someone's heart to its core.
