Siheyuan: My System Is Really Weird

[No harem + no female lead + a ruthless edge + the male lead focuses on his career and doesn't suck up to anyone in the courtyard]

One day in 2023, Qin Weiguo is working on an assembly line when a System glitch causes him to transmigrate into the courtyard, where he takes the place of a man with the same name.

How will he deal with the beasts filling the courtyard?

On his first day there, someone frames him, then causes a scene at the clinic.

On his second day, a widow comes knocking.

Silly Zhu gets jealous of Qin Huairu getting close to him and sees him as a rival in love.

Then comes the third day, the fourth day... In short, ever since Qin Weiguo arrived in the courtyard, there's been no peace. See how he gets out of trouble and carves out a place for himself in this unfamiliar era.
