The System Wanted Me to Be a Landlady (GL)

Hardworking, capable, beautiful, and kind Tang Zhi supported her family by farming and selling vegetables. She and the lazy, idle good-for-nothing next door, Song Yuyan, who always stole vegetables, had always been deadly enemies. When they met, they could quarrel endlessly. Until one day, Tang Zhi found out that Song Yuyan started to earn money to support her family, gave her gifts, and did not talk back when she scolded her…

Tang Zhi (vigilant): What do you want to do?

Song Yuyan: I want to support you.

Another version of the synopsis:

Song Yuyan, a top engineering student, just wanted to daze off during overtime, but the system regarded her as slacking off and dragged her into ancient times. She became a poor lowlife with the same name who was facing the threat of death. The system required her to reach the peak of life before she could return. To escape the predicament, she had no choice but to use her professional expertise—straw weaving, bamboo weaving, carving, candle making, building sea dikes… Accidentally, on the road of struggle, she became a small landowner and also achieved HE with her deadly enemy and childhood friend next door.
