My Overprotective and Naughty Sisters [DL Ver.]

Synopsis

The protagonist is the youngest child and only son born into a family of four older sisters. Having finally been blessed with a baby boy, his sisters showered him with affection—and as he grew, their overprotective nature only intensified rather than diminished. His eldest sister works as a school nurse, his second sister as a P.E. teacher, and his third and fourth sisters as upperclassmen. All four attend the same school as him, spending their days together both at home and at school.

One day, the results of the protagonist’s health checkup at school shock the eldest sister: his growth rate falls below the average for his age. An emergency family meeting is called. “Perhaps our brother isn’t growing well because he lacks proper nutrition… But we’re so careful with his meals already…” “A baby needs mother’s milk to grow properly. Shouldn’t we try nursing him?” With no parents to protect him, only his sisters can help—so they resolve to support him however they can.

The sisters obtain a mysterious supplement called “Bonyu de Ma Cool” to produce breast milk. And so begins his new life of being nursed by his sisters…!
