After thinking about it. My theory to doctor-sama and why she helps the dudes, even she is the Endboss
She is training the brats to suppress coming, because if it happens they will have so much inner pressure that she can harvest the ultimative gem, when they endured the no-fap only long enough.
I bet you a buck 50 that this dude would be snot-nosed crying on his death bed after cumming a whole lot. Plus, he can't go calling people who don't wanna fucking die idiots, what's stupid about wanting to live?
