Not just a remake of the 1993 version; it takes place at the same school, but with different characters and situations.

Both are slow paced, poignant films about North Korean defectors. Both portray the MLs' relationships with their mothers.

TEP had the folk fantasy elements that SToTD promised. Their similarities in this sense lie mostly within the first case of SToTD, including...
- Lots of martial arts
- Dark culty vibe
- Forsaken brides
- Demons of all kinds
- Two bickering men

Both dramas start with two classmates falling in love and one of them tragically dying and mysteriously back to life, making them experience what could have been and ultimately coming to terms with everything and being able to let go.

Differences:
Eien no Kinou is a BL.
In Boku Dake ga 17sai no Sekai de, there is a time skip of several years, before the decaesed comes back.

In both dramas a group of people find themselves at a strange place without any way to contact their home or families. They are trying to survive and find a way back while forming their own social dynamics within their group.

The FL has a passion for dubbing (not singing)
She is cute and hardworking

The ML is a bit arrogant CEO-type with a heart of gold
He has a secret identity

The FL struggle to enter the industry and the two fall for each other.
There is also some funny moments with the second leads. It is sweet, funny and charming.
I would argue that it is better than "My Special Girl".

Very similar premise but Live is a Korean production…. Very realistic, but I actually preferred the Live plot. It had a lot more depth… and I really ended up crying….

Both drama is romance about teacher & student with age gap. Forbidden love theme. Male student and female teacher.
