Little Joy

1. Time Travel: Both dramas incorporate time travel as a central plot.

2. Romance: The romantic elements are strong in both series. "A Time Called You" revolves around Han Jun Hee, who is deeply affected by the death of her boyfriend and finds herself in the past, as she makes effort to change the future. Similarly in "Lovely Runner", Ryu Seon Jae's death deeply affects Im Sol and she also finds herself back in the past as she now tries to change the future.
3. Emotional Depth: Both dramas show into the emotional struggles of their characters. "A Time Called You" explores themes of grief and longing, while "Lovely Runner" balances all of that with light comedy.

They're both noona romances.
Same actors (well not all of course just a noticeable few)
Same vibe and kind of music
Same realistic romance
Same directors
And dare I say same red umbrella. It's a paid actor at this point. LOL

Both 'Smile to Life' and 'Sunshine of My Life' have love triangles! The second male lead and the main guy who used to be best friends in each drama have a falling out, which makes things even more complicated when they both fall for the same girl.

- Both dramas involve a male lead who has a dark past and a secret identity related to a psychopath.
- Both dramas feature a female lead who is a police officer and who falls in love with the male lead without knowing his true background. They don't get married in HE IS PSYCHOMETRIC though.

The differences:

- HE IS PSYCHOMETRIC has a supernatural element. The other male lead can read people's secrets through touch, hence the psychometry. FLOWER OF EVIL does not have any paranormal aspects.
- HE IS PSYCHOMETRIC is more light-hearted and humorous at times, while FLOWER OF EVIL is more serious and tense throughout.

I'm pretty sure anyone who has watched Hometown Cha-Cha-Cha was reminded of it while watching Welcome to Samdal-ri simply because they're both healing romance dramas set in a seaside village. They also both feature a female lead who moves from Seoul to the countryside after facing some difficulties in her career.

While watching "Welcome to Samdalri", I was reminded of "Call it Love" because the male lead's father in Welcome to Samdalri was against his relationship with the female lead because of the grievance he had with the female lead's family while in Call it Love, the female lead's family was against her relationship because of the grievance they had with the male lead's family. So, in both dramas the main leads had to struggle through these family issues and heal to finally be together.
However, "Welcome to Samdalri" is lighter and more heartwarming, whereas "Call it Love" has a more serious tone.
So, if you enjoyed the healing aspects of "Welcome to Samdalri," you might find "Call it Love" enjoyable despite its more serious tone.

Both dramas are romantic melodramas that explore the challenges and joys of love and they both feature a main couple with a significant age gap.

They're both 2023 dramas that feature leads who travel back in time from 2023, and get involved in the lives of their younger parents or relatives.

Both Mom Wow and Nothing but Thirty are Chinese dramas that focus on the lives of women in their thirties who face various challenges in their careers, families, and relationships. They both explore the themes of motherhood, female empowerment, friendship, and self-growth.

TOMORROW WITH YOU and WHERE STARS LAND both feature Lee Je-hoon as the male lead. They are also both romantic dramas with a sci-fi element. The two series have similar themes of fate, secrets, and sacrifice.

Both I’M NOT A ROBOT and WHERE STARS LAND star Chae Soo-bin as the female lead. They are also both romantic comedies with a sci-fi twist. The two series have similar themes of love, trust, and overcoming obstacles.

Lee Ji Hoon in both dramas plays the role of an ex who returns from outside Korea back to Korea, of course, to get back together with his ex (FL) who is trying to heal from the heartbreak caused the breakup. The FLs in both dramas however move on and fall in love with new men.

Dinner Mate, however, is more mature and ends up with dealing more serious matters like mental health and healing from trauma and heartbreak basically.
