A Matriarchy? Why Didn't Anyone Tell Me There Was an Inner World Plot?

After Su Qi arrived in a matriarchal world, she lived a peaceful life of only teasing people without going all the way, never once suspecting anything was amiss. Except that she had a childhood friend she'd always been close to, who was rather frail and introverted, and unusually fit the profile of a cuckolded victim. Then one day, Su Qi came across some magical gadgets that had no business being on this set: a pocket watch that stopped time, a hypnosis app, an invisibility badge... Only then did Su Qi realize something. This world seemed to have some very messed-up storylines.
