Hello! The things I can remember about this novel is that the MC transmigrated into a book. In the beginning he was in the hospital since on OG MC was in a accident during his filming (I think). MC was seen by the ML when he was in the hospital and MC saw him and was fascinated by his looks. Current MC knows that OG body had a marriage contact but the ML wanted to cancel it and give compensation money. MC was looking forward to getting the money but ML changed his mind when he saw MC and wanted to met face to face before giving anything. MC saw ML and did not want to cancel the marriage since he liked ML appearance. In the book MC was a cannon fodder but now he became friends with protagonist shou. I think this novel was about also mpreg. That the protagonist shou was able to become pregnant. MC did not think that he could also since he thought that only shou could become pregnant.
I finally found the novel I was looking for Did some hard digging in jjwxc. Name: 豪门老男人的炮灰男妻 Unfortunately it is available only to be MTL
