Recommendations

Both stories:
* are short and sweet
* have fantasy elements to aid the female lead
* have a pretty male lead and a plain female lead
* have a love triangle

Mystery, other-worldly, reincarnation, love, friendship, BL, bromance, separate entities living in the same world, loyalty

Ghosts, supernatural, love, mystery. Similar themes of death and after-life. Some similar themes of romance

Themes of the supernatural, other worldly love, ghost and spirits and friendships/ loyalty. Similar tropes and themes.

Same concepts all around can't spoil b/c it would ruin the entire movie.
However, what makes it alike/different:
1. Male/Female lead fighting evil
2. Obvious titles give you the setting
3. State of the existence of the lead males are exact
All of the above works for Ghost Ship recommended.

All of the above works for Train of the Dead which I will Recommend.

If you like (Fall In Love At First Kiss), then you may also like (Mateor Garden). It is the
same feeling.

The synopsis about a brother in jail who allegedly murdered someone and how it affects the protagonist's life is the point of similarity between the two works.
A sinopse sobre um irmão na cadeia que supostamente assassinou alguém e como isso afeta a vida da protagonista é o ponto de semelhança entre as duas obras.

Both are very disturbing where an older character is living with an underage school student and having sexual relations with, both give off the same feel and are very taboo

Very funny scenes with a very confident female lead. She does what she wants and always gets into weird situations.

Both male leads act like dogs/puppies. This one is more like Tarzan though.
Older woman/younger man age gap

Another one minute documentary of the LOONA girls, only this time, it focuses on them during their off time, rather than whilst they're working, showing another side to the girls.

I can't spoil the story b/c their the same excluding two separate things, one being glaringly obvious:
1. Ones on a ship, the other is on a boat
2. In Ghost Ship, the leads are dating. In Train of the Dead, they're not.

Both has a very similar premise, in both dramas two leads are revived in bodies that are in contrast to their previous bodies and they try to accept new bodies and work through their new chance at life............

They both deal with an MC who was previously involved with the military and is now trying to live a normal life as they deal with a traumatizing death in their past. They are then dragged back into fighting through meeting new people. Both shows also have awesome fight scene. But The fiery priest does have more humor then k2. Both are good shows.
