I'm not sure if it is just me, but there appear to be no female characters in this story (up to raw ch. 172). No reference to any girls, mothers, sisters, maid, nothing... This story is kind of a sausage fest. As for the story itself, MC is a transmigrator from earth who transmigrates into a dying magic world, just to be transmigrated again back in time before the collapse of the magic world. MC lands into a well off family but has to start from scratch after his father dies from an accident. MC uses the knowledge acquired from the dying magic world to become OP.
