Minha Nossa, Fantasma (2015)

Bong Sun, a timid young woman, is possessed by the ghost of a lustful virgin. Her grandma was a shaman so. She’s used to seeing spirits, she meets the lascivious ghost that she gets possessed totally. bong sun is a kitchen assistant & she’s not really good at anything at all.. Sun Woo is a conceited star chef who’s overflowing with confidence in his food and his skills. Bong Sun harbours a secret crush on him, but he eventually falls in love with her

Both stories have female leads plagued by the ability to see ghosts and desperate to find a way to make it stop.

just first to say that they are very different but when I watched it there were some aspects that felt similar, these include:
1. boss/ employee relationship between ML and FL.
2. the FL is interested in food/cooking as their career.

1. They both take place for the most part in the kitchen.
2. The ML are both skillful Chefs that can be both arrogant and adorable.
3. FL end up working for the ML in their restaurant (and learning from him).
4. In both, the relationship between the lead starts off as a bit of love and hate; with the ML being very demanding in the kitchen and have little patience. As the show progresses and the ML becomes aware of his feeling, he becomes more patient and gentle with the FL.
5. They both have comedy, though Oh My Ghostess has a lot more.
6. There's a love triangle in both shows.

Big differences:
1. Oh My Ghostess has a supernatural element to it (having two main female leads pursuing the male lead, though one is a ghost). The show also has a crime element to it that gains strenght during the second half.

Both dramas have a restaurant background.
The male leads are chefs and own restaurants.
The male lead help female lead with finalcial problems.

This drama is a love story between Kataoka Sakuya, a grim reaper who comes to the human world for the first time, and Mochizuki Nayuki, a woman who lost her father at a young age and has devoted her life to raising her only remaining family—her younger brother. As they meet, they gradually come to understand each other, and slowly, they begin to fall in love. However, a fate that will dramatically change their lives awaits them both…

Both have to do with supernatural powers. Both are absolutely hilarious and brilliant love stories. Both give me the same emotions. Never have I found a rom com to bring me to top emotions like these two. Very well written, witty, and make you wish they never ended!

Each drama has different storylines but they have a similar vibe to each other. They are both very funny and the main male lead in both dramas is Jo Jung Suk.

The ML of Goodbye Again has stated that he referenced "Oh My Ghost" in preparation for the spirit possession his role called for.

Both of them are comedies related to ghosts and possessing, so you can check it out.

Soma Yui and Torino Naoki were childhood friends, but they met again as adults. Just as he decides to propose to Yui, Naoki suddenly disappears from Yui's sight after being embroiled in a mysterious incident. Naoki continues to wander in this world as a spirit without knowing that he has died. Naoki asks Uozumi Yuzuru, a detective who is the only one able to see Naoki, to convey his feelings to Yui, but Naoki ends up breaking up without properly saying "thank you, goodbye, and I love you" to the person he loves the most.

A love from beyond, that's what you'll see in both of them, in addition to a lot of humor. Hope this helps.

They both feature a person who can see ghosts that meets a ghost that can't remember who they are or how they died!

In this series you can see a group of people catching the ghosts with their supernatural power with the help of other world

the main similarity between the 2 dramas was that they both revolve around one character dying but becoming a ghost to deal with their problems before being able to be reborn.
