Princess

A princess, not cannon fodder.

Generals always meet their true love while away on campaign, yet marry a princess when they return to court to receive their titles.

The king whom a princess marries for a political alliance has always cherished an unforgettable first love, who even lives in the harem.

A princess who marries down may be the principal wife, but the prince always uses her to take a blade for the beloved secondary consort.

Born noble and precious, these princesses were cherished and spoiled by the emperor and empress from childhood, yet in the end they all became mere background characters in someone else's story.

Before her elder sister left to marry abroad, she told Yuan Shan, "The General Song you love isn't the right man for you. You should stop loving him in time, and not follow in my footsteps."

Yuan Shan's response: I don't believe you.

Until, after being killed in an endless cycle of reincarnation, she learned that her husband was behind it all.

Yuan Shan: I believe you now.

An irresponsible, unserious ancient-style romance about a little princess going through countless full-save-file reincarnations to torment scoundrels and get revenge. =A=

Definitely starting in 2019 [I'll set myself a goal in October!]
