The Fourth Book by Chai Ji Wudi Ma

[Sweet, gentle, clear-headed young widow VS celibate, dangerously intense, tough military officer]

[Mutually devoted in body and heart + Size difference + Intense push and pull + Sweet period romance]

Su Man transmigrates into a military family compound in the 1970s, becoming a new widow whose husband supposedly died because of her. To make matters worse, her in-laws are pressuring her to marry an elderly widower.

To keep her job and home, she turns her attention to her younger brother-in-law, Lu Lie, who has just returned from the border.

This man wears his military uniform buttoned to the top. He’s famous for being cold, stern, and uninterested in women, and he always looks at her with scrutiny and distance.

Everyone in the compound is waiting to see Su Man get thrown out by her iron-fisted brother-in-law.

But one night, Lu Lie doesn’t kick her out. Instead, he pulls on a faded racerback undershirt and, still damp with sweat, corners her behind the door. His rough fingertip brushes over her lips as he asks in a hoarse voice:

“Sister-in-law, our family has an old custom called ‘raising an heir for both brothers.’ Now that Big Brother is gone, shouldn’t I take his place?”
