time looping for the main characters that need to resolve the issue/unravel the mystery. One minor issue with Reunion is - it does not resolve much but it gives us an ending where both parties will finally work together using the remaining lives left to fix whatever needs to be fixed. Perhaps in season 2?

how to come to terms with being different and hated by most? How to love someone who is different and hated by most?

This is a story of struggle and fight for equal rights and freedom of those who have been enslaved/captured. And it requires a lot of work and moral spine to do what is right.

we have a smart girl with charms' skills and a martial arts master married to a hostage prince who actually met the first one and liked her, but then was decreed to marry the other one who resents him. Trying to figure out how the leads will reconcile the "triangle" will be fun

revenge story in both cases but RftA has a FL that managed to be a likable one whereas in The Lady Commander I understood the anger of the FL, but could not find her methods kosher

More than one person gets reincarnated into the story filled with unrequited love, hatred and sweet romance

Love story and marriage of demon lady and a man who loves her with all his heart. Fragments of Kylin had stunning scenery and interiors. This was a much lighter (more comedy) series.

the story of lovers from two different realms: demon and human. I actually liked this better than big production with big stars

If you want a really great revenge story for a second chance life, check out Rise from the Ashes!!! It has a clever plot much better than The Double, and while a miniseries of 10-minute episodes it is done in a superb way with brilliant script, really good characters as written and acted and the heroine there is a thorough kick ass!

the story of two people with feelings for each other and just having a contract to live together. And there is a cat....

It is the story of female empowerment what these two series have in common. BiA has definitely more modern feel...

the idea of poison and transfer of it was very creatively used in Butterflied Lover. Double Life is not about the same thing but uses the main character's dilemma with the poisoned beloved...
