@moel It's something that a lot of manga ignore when they do their "protagonist wakes up a thousand years later" thing. It would be so much more interesting if they explored that aspect of the timescale, but they never do. They always just sort of hand wave it away with "Oh, magic thing" or just ignore that this phenomenon occurs entirely. I just get disappointed with the missed opportunities.
Ah yes the ol' yuri bait because mc is a eunuch trope. If the trope didn't have the requirement of an mc with no libido I wouldn't mind it much but its just used to inject ecchi into stories because men in manga CAN NOT be in relationships for some reason.
