What's more tragic than traveling through time and becoming a female supporting character? That is to travel through time and become a male supporting role. Forget about the male supporting role, the saddest thing is that when you travel through time, you find that this body is still that of a cannon fodder male supporting actor who just had a night of sex with the heroine.
I can tolerate all this, but can anyone explain why the heroine looks at her harem with lewd expressions from time to time? Not only must he desperately avoid the fate of being cannon fodder in the harem, but he must also be hunted down by various nominal love rivals. Is the story of the male supporting actor destined to be so tragic?
If a woman crosses a male and enters by mistake, there will be no harem in 1v1, no harem, no harem.
