Both have an optimistic and strong FL, a ML who comes from the city, and a countryside setting.
..........................................................

Both are fluffy and healing short stories with a beautiful countryside setting.
.............................................................

One is BL and the other M/F but both have a city person ending up in the countryside and unexpectently falling in love with a farmer. Both are light, sweet, and have pretty scenery.

Both dramas are showing protagonist who is struggling with sports career,but with hard work manage to achieve something.
Both have comming of age/slice of life vibe (25-21 is more sad tho)
Both are having sad and very funny moments
And both have nice slow burn romance

"Heavenly Forest" is about a photographer named Makoto, who travels to New York during Christmas to look for his best friend, Shizuru. The two first met when Makoto attended his university entrance ceremony. Makoto tends to shy away from other people, but Shizuru made him open up to her. Because of their friendship, Shizuru also took an interest in photography; the two often went to a forest to take pictures. Shizuru wants nothing else but to be by Makoto's side so when he starts liking another girl called Miyuki, Shizuru decides that she too will like Miyuki and becomes her friend. One day, Makoto asked Shizuru what present she'd like to receive for her birthday. Shizuru, who wanted to enter a photography competition, had an idea to take a picture of the two of them kissing in a forest. Makoto agreed to do this and the two kissed for the very first time. Ever since that day, however, Shizuru disappears from Makoto's life.

At 17, Wen Heng who was an adopted child, was finally found by her biological parents and brought back to the family home in Beijing. There, she tries to adjust to her new life with her new family but problems occur when her adopted sister felt threatened by her presence and started throwing tantrums. In an effort to keep the peace in the family, Wen Heng was asked to move into a family friend's house next door. There, Wen Heng meets Yan Xi and the two of them slowly start to grow closer as they live together and go to school together. But this happy life didn't last long when Yan Xi has to return to America to be with his sick mother.

Vampires are topic and vibe is very simmilar. Both are romantic with comic moments.Out of all vampire drama those two are the most simmilar.

Ghosts theme is a main theme of two dramas. In both dramas one of a leading characters is able to see a ghosts. The seeing character in these dramas can protect themselves from ghosts by touching and being present with the other leading character.

When romance is thrown in the turmoils of history.
Both dramas start like your typical romcom, boy meets girl, girl dislikes boy... (Granted, in My Dearest the FL is wearing a hanbok while in Youth of May, she's running around in jeans.)

But then, history with an H intervenes. For Youth of May, the dictature and the shadow of the Gwangju massacre are looming over the happiness of our protagonists. For My Dearest, it's the Qing invasion that sweeps them away. So, if you like a *somewhat* realistic period piece that isn't all political and that still has time for some cutesie lovey dovey stares between the lead, these dramas are for you.

In both you have the perfect balance of lightheartedness and Melo

The FL is also frustrated and annoyed at the ML to the point she wants him to die. Her plan to kill him fails and the ML ends up getting amnesia. So she starts pretending that they are in a loving relationship. In the end they fall in love for real.

This may sound ridiculous. But these two have a lot in common:
-reborn again
-correcting mistakes
-not escaping reality
I can't say any more since it will give major spoilers but do give a scent of time a chance. You'll be pleasantly surprised.
