Recommendations

Although I would like to say season 1 and 2 are different in story line but the concept is still there. I recommend both seasons because it entails life lessons and different medical cases. It portrays realistic situations and good research.

They both discuss the idea of single moms and marriages connections to the idea of being a good parent. The difference is in Ho Goo's love the baby is already there and was an accident while in Oh My Baby is about the planning for single motherhood. There is also a love triangle theme in both of the dramas.

Similar setting of a larger than life female lead, given a punishment to deal with humans.

Both have a strong supernatural element, although I would say HDL focuses more on the afterlife. MPUB has potential to touch more on the theme as the series progresses.

Similar ‘human or story of the week’ style to the episodes with an over arching plot across the series.

HDL has more of a cemented romantic plot whilst MPUB focuses more on the trio. However both have a family theme.

Both dramas deal with subject of social outcasts and how they came to feel that suicide was their option.

Both are stories that involve mysticism, souls, past lives. There is a female protagonist who is angry, "selfish" and firm, on the other hand a male protagonist who is sensitive and puts herself in the shoes of other people and "innocent". There's comedy. They'll solving cases to help their "clients" to release the soul of the female protagonist.

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 involve office romance between a girl and three or more men who are vying for her affection in comedic and sweet ways. Feel good, warm, happy dramas that you can watch over and over again

Both are love stories between an older male professor and a younger woman. Her Granddaughter is much calmer than Papakatsu though (if that makes sense...?)

Eccentric Male Lead, Romantic Comedy Done Right. It has the same vibes how the relationship of the leads improve and conquer for them to have a happy ending.

A modern day remake of the original 2008 Taiwanese drama, Fated to Love You. It will follow a similar story line of a plain, average girl, who accidentally sleeps with the wrong man and becomes pregnant. The man, a big CEO of a large company, who was planning to propose to his longtime girlfriend (but gets stood up) is then forced to get married with the girl he accidentally impregnates and thus begins their long road to eventually realizing that they are each other's destiny.

A similar setup for the plot! A woman from the past with a tragic backstory who is immortal/dead must grant wishes/put people at ease in order to fulfill her duty and pass on peacefully. She does it with the help of the main male lead who gets thrown into it all. She is tough, surly, and just SO done. Pop-up bar seems to be a little bit more comedic than hotel so far.

Both the lead main roles are about a fashion designer that has found themselves in big trouble. The storyline is also a little similar, however, the plot is completely different. I think "love designer" is a good binge-worthy drama to watch during quartine.

both ml have a gaming company and the plot revolves around game development a lot
both have pre good chemistry

plus xing zhaolin looks kind of like yang yang ahahhaah

When I think about ghosts and mystic things, the first drama that comes to my mind is A Korean Odyssey. Both of them deals with a strong female lead and mystical events with funny scenes and great characters.

both are two cute romantic minidramas. In both there is a couple with an older female and a younger male (although in Love Playlist said couple doesnt have any real screentime in season 1 but the following ones). They also talk about unrequited love for abit and just generally give me a similar feel
