I Transmigrated into a Book Set in the Seventies, Won a Military Officer's Heart, and Started a Family

Growing up in a family that favored boys over girls, Song Yu became the kind of woman who bent over backward to support her younger brother. It took an accidental coma for her to discover that she was living inside a book, and that her lazy, freeloading brother was actually the male lead. In the future, she would be vilified for refusing to give her job to him. She would also marry the wrong man, end up homeless, and survive by scavenging trash before dying miserably. Meanwhile, thanks to the male lead's plot armor, her brother would seize every opportunity, grow rich, and live a life of glory. Song Yu: ??? Fine, fine. If she couldn't afford to cross them, she could at least stay away! Whoever wanted to support that brother could do it. Song Yu turned around and latched onto the sturdy thigh of a certain regiment commander. What? The military base was on an island, far from home? Perfect! She wanted difficult travel and complete isolation! Far away from her biased parents and wayward brother, she could live peacefully on the island, raise her child, make money, and be spoiled by her husband to no end.
