Chapter 1

Living abroad, our two college-bound brothers nearly strayed down the wrong path. To protect their education, I—alongside another guardian sister—devised a daring plan.

Late at night, I slipped out of bed and tiptoed toward Sophia's brother's room, ready to fulfill our secret pact between sisters.

My name is Evelyn Laurent. At 26, I’m a guardian sister abroad, juggling doctoral studies while caring for my younger brother.

We share our home with another sibling pair—Sophia Evans, a nursing mother with a ten-month-old son.

Her brother, Ethan Evans, and my brother, Oliver Laurent, are both freshmen at the same university.

We come from single-parent households. Originally, our father was responsible for Oliver, but he relocated here for Africa aid construction.

Sophia’s husband, Daniel Winston, is also part of the same project. For convenience, Sophia brought her infant son and younger brother Ethan along—their parents having passed in a car accident over a decade ago.

Since our brothers attend the same university, study the same major, and share similar backgrounds as fellow expatriates, we rented a four-bedroom apartment together upon arrival.

Sophia, now 30, possesses striking curves—her nursing period only enhancing her natural beauty.

Though unmarried and childless, my own figure has always been full and shapely, nearly matching Sophia’s postpartum glow.

With both our fathers and Sophia’s husband working overtime at the construction site, our household consists solely of us four—plus Sophia’s baby boy.

Raised in the countryside, Sophia nurses openly without hesitation. Even when Oliver does homework in the living room, she casually lifts her blouse to feed her child.

This habit flusters Oliver—still inexperienced in life. Each time I catch him stealing glances at Sophia breastfeeding, embarrassment floods me. Noticing my stare, he blushes furiously.
