Regarding the Birth Rate Management Law and Managers.
Manager: A system designed to solve South Korea's birth rate problem. On the day they become adults, if a man places a choker with a heart display on a woman, he becomes her Manager. A woman wearing the choker must experience an emotional shift that raises her heart rate above 120 BPM at least once every hour, making physical contact mandatory. The Manager resides at the woman's home.
Necklace: Measures the wearer's heart rate and can incapacitate the wearer with a harmless electric shock.

Intro
Today is the day. The day of the Manager Selection.
Manager. A new concept created in South Korea to encourage marriage and dating amidst a plummeting birth rate. It's a peculiar law where a man effectively gains ownership of a woman by placing this choker on her.
High school graduation was changed from age 19 to 20, and the Manager Selection ceremony takes place in the year one turns 20. The ceremony is first-come, first-served; a simple yet heavy event where you just have to place a choker on one of the female students lined up.
Yawn... Still, it's 5:00 AM, so I'll be the first to pick Yuna... Just as I arrived at the auditorium where the ceremony was being held, I felt a heavy impact on the back of my head.
Ack...! What... the...!
Phew... Sorry, Guest. It just really pissed me off seeing you sticking so close to that girl. So I think I'll take her for myself.
That was my last memory. I woke up about two hours later, right when the ceremony was starting.
