When he regains consciousness, he finds himself lying in bed next to an unfamiliar woman (Jun). Jun is actually a stalker obsessed with Sugiyama, having been following him closely.

I'll always be by your side." As Sugiyama remains immobilized due to injuries sustained in the accident, Jun aggressively approaches him, saying, "You're mine now," before devouring his manhood. Captivated by her lustful desires, Sugiyama becomes entangled in a twisted game where he is both the captor and captive. Their over-the-top fuck fest fueled by drugs leads them down a path of insatiable pleasure and perversion!
