Madogiwa Henshuu to Baka ni Sareta Ore ga, Futago JK to Doukyo suru Koto ni Natta

"We'll let you do all kinds of wicked things with us—if you agree to let us stay." Mitsuhiko Okaya was an utterly ordinary man whose life had fallen apart. Betrayed by his wife and a junior colleague, he found himself the subject of mockery at work, dismissed as a worthless editor and left to sink into hopelessness. Then, on an otherwise unremarkable day, a pair of twin high school girls he had never met—yet strangely recognized—appeared before him. The younger sister, Akari, was effervescent, bright, and endlessly fond of teasing him. Her elder twin, Nanako, was shy and awkward, though beneath that demure exterior hid a secret pervert. They were, in fact, former students from the cram school where he had taught during his own university days.
