Both shows are xianxia dramas and have a demon male lead.
The female leads are also from the immortal realm or aka "good" side.

Same genre. Good love story, one of the most popular. We are watching this for those, right? Love between a human and a demon. Kind characters.. I would say will put on the same shelf with the Ancient love poetry, Ashes of love, the Untamed, legend of FuYao, Immortal samsara, Eternal Love of Dream.

Love, destiny, sacrifice.. I would say if you like one drama, would love this one as well. Good plot, graphics and very similar story but yet different. Live with characters.

They both have an age gap, and the male lead is younger than the female lead.

These are stories with reincarnation of drama characters involved in a romantic relationship. In "See You in My 19th Life " the female lead is born again and searched for his previous life important person who becomes his romantic interest in current life. In "To all the Guys Who Loved Me" the leads had an unfortunate relation in previous life and a lot of incidents happened that male lead felt should be corrected. So in both dramas one of the leads used a past life information to built a better current life

Even if one is medical drama and other is not .

There are supernatural elements in both.
Both dramas have fantasy and comedy elements.

Main similarity I find is Bromance in both dramas. Its hilarious.

Both shows are medical dramas.

There is also mentor mentee theme in both drama that I love.
Both dramas have smart and strong MLs.

They both have a character being killed and the sad consequences of it on the family (who is innocent) of the killer and the sorrow of the victim's one.

They are both based on the same novel, each country gave their version a different tone.
I think it's always interesting for the viewers to watch both and decide the pros and cons of both.

Both are slice-of-life dramas that are light-hearted comedies. The main characters give off similar vibes even when one of them is serious about life and the other is happy-go-lucky.

Another family business drama with very similar plot and characters. Wayne Lai is even more funny in this one and Steven Ma was a fantastic lead.

Both genres are similar in the way that the male lead falls for the same soul in different bodies…


PS. You’ll have to first watch season 1 of Alchemy of Souls if you weren’t aware that it exists.

Both dramas are filled with action and adventure. Both are also set in historical setting with wuxia and martial arts elements.

Both are mini dramas in which the FLs loses her memory of a night/the past and has raised her young son alone. Unexpectently, she enters into a contract relationship with the ML, later learning he's her son's father.

Both FLs are drugged and have no memory of the night they spent with the ML. They have a son as a result of that night, and search for the father, ending up involved with the ML in the process.
