"So you came all the way here"

Here, they held the largest black market auction in the United States--the Imperial Auctions.
Unknown to the public, all laws are exempted in this place.

The protagonist, Kaho Yamashita, steps onto this stage of human trafficking with a particular intention...

"It's been a long time...and...I see that you've changed your clothes..."

The successful bidder for this auction was the Asia's greatest mafia's surrogate boss of the U.S. division, Wang Wei.

Kaho remembered that Wang Wei had bullied her relentlessly back in high school.

"Why are you standing up and talking to me? You're my property now, aren't you?"

When they met again, Wang Wei treated Kaho not as a former classmate...but as an object.
He made Kaho wear a chastity belt to control her urination, and even inserted toys into her body in public...as if she is just a sex toy.

Reminiscing his past bullying, Kaho confronts Wang's psychotic behavior.

Madness, love, and obsession intertwines within their relationship, then...

"Welcome back, Kaho"
