Immortality or The Husky And His White Cat Shizun, is a live action base on a BL Novel. Sadly the drama wont be out until 2021 spring, but in the meantime you can listen to it's CD Drama and read the novel, it does have a Manhua but I haven't found any English translation or a place to read it.
If you also know and enjoyed Scum Villain Self-Saving System (another BL novel) then I would like to think you will enjoy this!
It follow our MC Mò Rán who's a disciple of Chu Wanning. In his past life he was the first Emperor of cultivation world, Taxian-jun. After his death he was reborn and transmigrated to the year when he first became a disciple of Sisheng Peak.

Poisoned Love has the same backstory as What’s Wrong with Secretary Kim? It is a 20-something Cdrama similar to the 30-something Kdrama.

Bridging the gap between two parts of a coming of age story.
Love found and love lost.
COVID-19 themes of isolation

Long lost relationships, friends becoming more in time, coming of age stories that match
Both stories have the same main star in a somewhat similar situation

High politics in an engaging way. Almost no romance to distract from the exciting bigger plot. Lots of characters to love, hate or simply love to hate. Close knit team of hardworkers coming together.

Both are exaggerated comedies set in a historical period. The characters are all quirky and lovable with great chemistry.

- The leads both try to overcome their painful memories
- Both female leads are trying to hide pain
- Both male leads are a little mean to the female lead at first
- Both stories are not really that complicated
- Both are melodramas, filmed in winter
- The leads both knew each other ever since they where in high school

Childhood friends, separated due to misunderstanding. Come across to each other after years. Started working together. Hate to love relationship. Beautiful chemistry. Rom-Com with drama and interesting plots.

1. Both dramas are about a contract couple
2. Both dramas have a love-hate relationship.
3. Both dramas have a rich male lead.

Their is a contract marriage.
Rich male lead
The female lead is building her career, being a writer.

Marriage of convenience, ML are both generals that have came back from war recently, FL keeps trying to run away at first, bickering couple, hate to love, cold ML/warm FL, light hearted rom-com, only a tiny bit a angst that keeps the drama going.

Main character also uses someone else identity due to complicated family issues.
She then falls in love and starts a relationship while hiding her true identity.
Mask is more about the lies and betrayal between the couple, their relationship is more complicated and not as stable as in Flower of Evil.

Both female leads dress as a man to hide their gender, trying to figure out who killed their family members and why. So check it out. Although I have started watching both, but never have been able to finish both, both are still pretty interesting.

No secrets has same story line as I hear your voice. Totally same. One can say it to be a Chinese version.

These two gave me similar vibes. Both are stories about two almost perfect people, no big drama, misunderstandings, difficult in-laws or permanently evil villains. Just a feel-good romance.
