The similarity in names is just ironic!
Similar feeling. The instant connection, the slow romance, the gazes, and the tension.
Beautiful dramas that focus on the romance, with a similar story.
Similar stories. A wounded man, and a girl in a long committed relationship who's soon to get married. They meet in a similar manner.
Of course OSN has a different quality since it is newer, but Summer Scent has a really good quality given the time it was aired.
Both are slow and quiet dramas.

If you enjoy these two main actors you will probably enjoy an older version of them during their new career lives! I don't know if it's just me... but "My Girl" seems like a sequel from "My Youth" with their older adult selves in another life (falling in love once again... with more romance and drama! Maybe it's meant to be...)!! Even the show titles are similar!! XD

Romance between a Doctor and someone working in the military. Dear Uniform hasnn't started yet but these stories seem to be very similar in terms on the relationship between the leads.

They're almost similar to each other. it gives off the same vibes from what is happening to Strangers from Hell.

Similarities:
- Trained MC (special forces/trained assassin)
- Action packed
- Revenge theme
- MC is somewhat emotionless until they meet a girl
- Troubled past
- MCs are good at what they do

Dissimilarity
- K2 = romance
- Kill it = friendship
- Kill it handles a dark theme (not reccomeneded for kids/under 15)

- ML has already a girlfriend
- One Night Stand
- Something happens to the (first) baby
- FL gets pregnant
- Marriage
- Rich Male Lead
- Poor Female Lead
- Might be more, but cant tell because YAMD is still airing and is not complete.

both female lead have crush on male lead in her early age their crush/love never decreases only increases day by day she follows him on every step from school , college to profession life . and only get rejection in return her love is so high for him so she never mind his ignored behavior. situation and people helped her to near him . she is daughter of male leads parents friend who is single parent and situation allow her to live her in his house.

-the MLs hating each other at first
- both MLs are smart and useful
-they are protecting each other
-slow paced of romance
-the FL is shameless
-the ML fall for FL first
-ML does everything for FL without her knowing
-anti cliche

Both female leads find out they're connected to royalty. Both shows start off from rags to riches, then suddenly they become royalty with money. Both Female leads have this quirky way of doing things, which makes sense, as they are learning how to live differently from what they've known their whole lives.

Story lines are completely different, but these two dramas just give you the warmest feeling upon finishing them. They both take you on an emotional journey and you can really get to know the characters.

Love with flaws also has a cute LGTBQ+ couple. It also deals with homosexuality with less of a conservative taboo response. One of the brothers is gay and runs a gay bar and no one really blinks an eye. He doesn't give a sh*t what anyone else thinks.

While Doctor John is more serious, I think these two dramas have a similar tone. The romance is similar, and both are sweet and heartwarming dramas about the medical world.

Both are short BL shows with main character(s) associated with gangsters. While red balloon differs in that the main characters are teens for most of the story, and it’s less intense than long time no see, both have very heartwarming and convincing relationships between the main characters, and interesting side characters.

2gether is the prequel of Still 2gether. It tells the beginning of Tine and Wat story from the time Tine asked Sarawat to be his fake-boyfriend until the moment they truly become a real couple.

-In Born Again, the leads become reborn and don't remember their previous lives until later in the show. In Goodbye My Princess, the leads meet but then lose their memories of each other, meet again, and then regain those memories towards the end of the show.
-Due to memory loss/being reborn, the female lead forgets that she hates the male lead (for very justifiable reasons)
-a semi-evil male lead who makes decisions against the wishes of the female lead that end up getting her hurt (physically and/or emotionally). Kinda obsessed with revenge on their family. In Born Again the male lead is also a major creep and (unfortunately) sometimes his actions are portrayed as romantic. But both do majorly bad things that are (or at least, should be) pretty unforgivable.

For the record, I think Goodbye My Princess is way better, but it is also quite different in terms of genre and tone. The other recommendations listed are more similar to Born Again.
