From the Kong Sang Continent comes the tale of the tumultuous love story of Princess Zhu Yan of the Chi Yi Tribe and Royal Prince Shi Ying,

The framing of the Queen results in the Prince being banished to Jiu Yi Mountain to cultivate. Once solely focused on his tasks, he develops romantic feelings for his disciple Zhu Yan. But their student/teacher relationship prevents either from expressing their true feelings.

Fate then works against them when they choose opposing sides in a political struggle of life and death proportions.
Eventually, putting aside their issues, they pledge to protect their beloved Kong Sang Continent.

Tantai Jin and Li Chengyin competing for the title "the worst ML in c-drama land".
The author of Goodbye My Princess also likes Jinjin a lot.

In both dramas the ML is weak and nice at first then they become "demon lords".
Both dramas are wuxia's with beautiful fantasy world.

The set up shares many similarities

- in both dramas, the female lead transmigrates into past (TTEOTM) or historical fiction (TROTaR)
- the female lead is kind but replaces someone who is quite cruel (and nearly crazy)
- the female lead is in a loveless marriage with male lead
- the male lead seems to have feelings for older sister of female lead (TTEOTM) or female lead tries to set them up (TROTAR)
- the male lead appears weak and docile

However, the vibes of both dramas are different - Tiger and Rose is very comedy centered while TTEOTM (while still not the most serious ever) has more some more somber themes and the stakes of the whole story seem to be higher

Amazing chemistry between the leads. Awesome cinematography. Great music.

Differences: unequivocal (and long) HEA for one of the dramas.

1. xianxia romance
2. main lead turns evil expect in TTEOTM it's the male lead
3. immortal sect/cultivators are involved

ML is demonic immortal
Fl wants to stop her from the bad things he is going to do
ML have sad backstory and painful life
ML is prince and sacrifice so much for FL
