How Could You Forget Me?

Zhang Hailou x Zhang Haixia. Major out-of-character characterization. If you don’t like that, don’t read.

As Zhang Haixia is on the verge of death, he transmigrates a hundred years into the future, after his own death. He discovers that many things have changed. Zhang Hailou has forgotten him, and he has nowhere to go, so he can only run a pocket watch shop and silently watch over Zhang Hailou. By chance, he meets Wu Xie, then joins the others on a tomb-raiding expedition.
