Both are xianxia dramas driven by a love story unbounded by a single lifetime. Many parallels can be drawn between several plot elements due to the same setting and genre, and comparisons can't be avoided. However both stories are their own!

I think that the delicacy and pace with which the main character's relationship develops is similar, so if that's what you've been captivated by in one of these titles, the second one can also appeal to you.
It is worth mentioning that both are well-directed - with particular emphasis on details - which I think is a very strong side of these dramas.
In addition, both affect the problem of coping with the loss of a loved one.

By the same writer and both have plot twists, things you never saw coming. Keeps you on the edge on your seat.

“What is yours is mine and mine is yours. ”

A bittersweet love letter to friendship.
Love-triangle.
That is sure to make you shed a few tears.

One of the best chemistry of the leads in any Asia drama with a statisfying ending! Breathless romance and good comedy throughout!

Both shows:
1. Are parodies of their genre, as such the comedy takes precedence over everything else.
2. Despite the absurdity, there's a good and heartfelt plot at its core.
3. There's a lot of character growth from the main leads.
4. Main leads establish a balanced relationship, in which they bot learn and get something from each other (rather than one having all the power).
5. FLs kick as in their own way. They don't allow anything to stop them, always take the initiative and are pretty active.
6. MLs are soft guys with a tough exterior and they trust and rely on the FL.
8. FLs have a support group of friends.
9. Antagonists/villains are over the top and slightly on the cartoony side (which adds to the hilarity).
10. There's a love triangle in both series, with a SML pinning for the FL.
