these two dramas are quite similar even though plots might be different
gives me mixed feelings for the main leads

- both male lead is related to the heaven/gods/deity
- both female lead are destined to die
- both male lead wants to save the female lead
- at the beginning, both male lead didn't much care about the female lead
- at the beginning, both drama leads wants the other to love them ( somehow ) to save their lives. [ A Korean Odyssey- the female lead put on a bracelet on the male so that the male " loves" her and won't kill her ] [ Doom At Your Service- The female wants to love the male lead so that she won't die and she won't lose anything that way too ]
- gives off similar vibes :>
•A Little Spoiler Ahead• ( not sure if this is considered a spoiler )
In A Korean Odyssey, the female was the one who died but the male went to find her at the other world ( other world?? i think- ) so if Doom At Your Service is similar to that, the ending should be the same at most ( either the male or the female has to die ) *NOT CONFIRMED, THIS IS JUST ONE OF MY OPINION*

-both drama the female lead male friends are jealous of the female and the male leads
-both male leads are smart and help the female lead with studies
-both female lead are jealous over a girl who is smarter than them and went overseas with the male lead
-both dramas include romance.school life

-Both female lead is aware of themselves
-both lead protect on another
-both drama involves comic
-both drama has happy ending
-both dramas in the middle of the story was sad

Closer to you is very similar to Somehow 18 just Closer to you is in chinese but somehow 18 is in korean.
Both female lead lean against the bus stop poles while listening to music,Both male lead is a outcast in school and both traveled back in time to save the female lead. Even the starting of Somehow 18 the scene is the same as Closer to you "ending".
Both female lead personalities is almost the same too and the way how they introduce themselves is so similar!!!

-Both is about ghost
-Both have jealousy between the main lead
-Both storyline is main lead disliking each other at first.
Nonetheless, each of them have their own storyline and is both amazing!!1 :D

The story line is pretty similar, protecting the other one from ghosts and last episode is also about after life so really recommend it!

The genre is almost the same but the story is quite different, nonetheless, Love O2O is really great :D
