Both are 2019 Thai projects.
Both have thriller, mystery, drama, supernatural elements.
Really well done and have the same vibe to them.
Anyway if you've seen one then you'll most likely like the other as well.

Both dramas has lead who are faced with an illness. The drama revolves how they cope with their illness and live with it. An inspirational journey.

These dramas are similar to each other in the autopsy and forensics side. If you want to see more similar you could watch all the series of Medical examiner Dr. Qin. There are more than ten and I am sure you will enjoy them.

Same themed : 2 dads & a child...both are sweet and a bit lovey-dovey too.

It’s a magical tale with the right portion of mystery and visual aesthetics. The duty of life but changing through a close and dear person and the fight against those who cross that with evil.
Loved both movies dearly and rewatched many times.

While the plots are not really too similar (apart from rediscovering a childhood connection), I felt like the leads from both dramas are just two sides of the same coin. All characters have childhood trauma. The male and female leads from both shows are so similar: rather reserved, but feel strongly about X topic. The MLs have flashbacks and are a bit cheeky, using it as a coping mechanism. The FLs only remember the incident near the end of the shows, yet somehow find themselves drawn to the MLs. The brother in TSHLYE and the ceo in JBL are strikingly similar too.
Somehow the feel of both dramas was similar too. Something about the pacing, camerawork, set design, lighting—it almost felt like I was watching the same story told from two different perspectives.
I’ve rambled about the similarities, and by this point you might think that they’re too similar to enjoy both. And while that may be the case for some people, personally I found that the plots were different enough, and by halfway through the 2nd I had stopped comparing them. (Date 210430)

Dark souls possessed humans whom have anger inside them , both of them talk about people who is trying to stop this , also the female lead in dark hole was trying to chase the one who killed her husband as same as the male lead in uncanny counter he was trying to chase the soul which killed his parents

both dramas are from OCN and the posters gave me the same vibe which is why I started both of them xD

both are OCN dramas, both deal with evil spirits, though in Dark Hole more people get "infected" by the evil spirits

Dark Hole is like a mix of zombies and demons ie a modern vr of joseon exorcist TT_TT
we'll never know how much similarity they'd have but I'm presuming this too has a big evil demon they need to get rid of

If you are into the theme of alternate universes - Well Intended Love 1 & 2 is perfect. I actually enjoyed season two better than I liked season one, and I really liked season one with all its dramatics. They did a really good job creating this alternate reality in season two where the world was the same but if the main female lead didn't miss her episode one audition and got the role, which kick-started her career that never took off in season one.

I didn't watch it yet, but the plot seems similar to The Girl Who Sees Scents. Maybe I should watch it right now

The stories were super similar, but the show business aspect of Bei Bei and Jiawei careers reminded me of The Brightest Star in the Sky and it honestly made me want to rewatch it. It made think how I wish they showed more scenes of Bei Bei being a career driven actress because all I got from this drama was that we were told that Bei Bei was this amazing actress, and we just had to believe it.

If you are obsessed with dramas where the rich CEO/ General Manager falls in love with a talented yet poor girl then both dramas are for you.

Similarities:
- Same male lead
- Similar female leads (I love that the woman in Sunshine of my life is bolder whereas the lead in Boss and me is shyer)
- Childhood family friend in love with male lead (and tries to break them up)
- Stay together once get together and fight for their relationship (Boss and me does have one break up)
-Male chases female first
-Many cute scenes and kisses
- Etc...

Veryyyy similar shows but I love both!

Made by the same staff with several returning cast members. Also, the nature of the relationship between the characters played by Tsutsumi Shinichi and Yada Akiko are very similar in both dramas.
