Omae no Kaa-chan, Mesubuta Nikubenki ni Nattenzo?

My mom had been hypnotized. She was convinced that some sleazy guy was the love of her life. Her thoughts manipulated, she started taking on ridiculous part-time jobs. "Hypnosis…? That’s ridiculous!! Please, Mom!! Snap out of it!!" But my pleas fell on deaf ears. She trampled over the promises she’d made to my dad, betrayed his trust, and the once-clearheaded woman I knew transformed into something unrecognizable—a shameless, lewd bitch.
