Transmigrating into the body of an ancient person doesn't have to be earth-shattering. You can stay home.
Transmigrating into the body of an ugly person isn't necessarily bad. You can settle into your homebody life even more easily.
Transmigrating into the body of a princess doesn't mean you have to fall in love with a prince. You can make the prince fall in love instead.
That's it. The heroine is cannon fodder, and the protagonist may be a little silly and naive, but I won't let her stay that way forever.
I hate angsty stories, so at most there'll be a few twists and turns in the middle. I absolutely won't make it tragic.
Keep up the good work, nothing has unfolded yet.
