What Should I Do If I Suddenly Travel to the Ancient Harem?

A mourning otaku actually traveled through time to the harem. She won't do it. She wants to come back alive. The daily running accounts in the harem are interspersed with the protagonist's psychology. There are occasional fantasy plots. -------------------------------------------------- A psychotic idea after a nightmare. The writing is useless, which can be seen from the author's virtuous way of naming people... The heroine is in mourning, so it is impossible to survive to the ending without a little bit of intrigue. No CP. But maybe there's a little ambiguity like Lily... If there seems to be any corny sarcasm in the article, yes, the author is being sarcastic. The ending is HE based on the protagonist's values.
