¡Hola y adiós, mamá! (2020)

Similarities:
- Both make me cry so much and feel so many emotions
- Well developed story with twists and turns, full range of emotions covered
- Well cast, great acting

Differences:
- The plots are completely different
- The Light in Your Eyes has a younger cast and emphasizes on romance in a different way
- Time Travel???

Both dramas are set around ghosts / the supernatural. Including both dramas are very heart-warming, and know a way in making you cry!

Both feature a ghost mother leaving a child and husband behind. Also, in both media the husband becomes depressed/suicidal due to the incident of losing their wife. Both have the ghost only visible to a select character.

It's the story of a mother who died and begins a 49-day long project of reincarnation, and a husband who has barely begun to live a new life after overcoming the pain of losing his wife. Jo Kang Hwa is a skilled thoracic surgeon. After losing his wife four years ago, he had been working as a single father until he got married again two years ago. While he seems like a caring person, he does not offer a hand nor intervene when needed.

They both have mothers trying to handle the balance between supporting their children and existing happily. Hi Bye, Mama has more dark and serious themes whilst Doctor Cha is slightly more comedy focused.

Both dramas are similar in the aspect of ghost seeing, supernatural elements and ghosts staying back instead of crossing over to protect their child. Even after death the main leads who are dead and now ghosts stay back on earth and protect their daughter from harm and resolve their regret.
The difference is in "Hi Bye, Mama !" the female main lead a.k.a mom ghost gets the opportunity to become human for 49 days and accompany her daughter whereas in "Who are you?" the dad ghost can possess the male main lead and help his daughter from behind the scenes without telling her that he is the ghost of dead dad who possessed the male main lead.

Both are heartwarming, funny, family dramas with a strong mother-daughter relationship. They show what it means to be a mother as well as the sacrifices that mothers make for their children.

Many scenes from Hello, Me! reminded me a lot of Hi Bye, Mama!, especially because the two shows depict a supernatural event that deeply affects the lives of a variety of people. What's more, both of them deal with parting.

"Hi bye, mama" is about a loss, a mother losing her child. Not for the fact that she can't touch, or she can't be with her child, but for the fact that for your child, you are not her mother anymore. The fact that you gave birth to her, doesn't change the fact of your absence in your child's life, and "Lie after lie" portrays exactly that. That your absence, even if it's not your fault, changes evrything.

Similarities
- Both dramas revolve around family, sacrifice and regrets especially the relationship between parents and children + spouses.
- Both dramas have a warm feeling to it.
- Both dramas are have a parent as the protagonist - father in 18 again, mother in Hi Bye Mama.
- There is no real villain
- Both dramas highlight some social issues. 18 again: women empowerment, teen pregnancy, bias in society, etc. Hi Bye Mama: bias against step moms.

Differences:
- While 18 again revolves around love and hurt on a daily basis within a family, hi bye mama is themed around the pain when one is lost to death.
- 18 again is a lot more realistic and relatable and has only one fantasy element to it while Hi Bye Mama has more fantasy elements to it compared to 18 again
- 18 again's driving regret revolves around what could have been done if family wasn't there while Hi bye mama's regret revolves around what could be done for the family.

- both about reincarnation
- the death of a spouse and parent
- both are fantasy and supernatural and comedy

Hi Bye, Mama! and Wonderful Nightmare have that reincarnation trail theme and both in the end are heartwarming family genres

Bith dramas reamly dig deep between the special bond betwezn a mother nd a child. However what makes Mother different is that the lead takes on a role of a surrogate mother for an abused child, trying to protect her from the corup parents.

Both of these dramas involve someone who is already dead coming back to life to spend time with family and friends
