Both shows have a really gritty, unfiltered depiction of people in poverty, downtrodden by their circumstances and random events that happen in the course of their lives. They also both show the reality of people trying to handle trauma and difficult things that happen in their lives. But both also have genuine moments of connection and commonality with others.

The first 9 episodes of The Light In Your Eyes are very similar in tone to My Mister. There's a certain destitution and downtrodenness, but at the same time, the show has moments of levity and emphasizes genuine human connections and relationships. The characters in both shows feel real, but they also both feel quite suffocated.

Somewhat minor spoilers ahead (Nothing that shouldn’t be expected if you watch the intros and outros or read tags on this site)
I know that the basic plots of these two stories are pretty different, but please hear me out. Maybe it’s because they were both by MGTV, but I found loads of similarities to share.
Intense Love and Love the Way You Are were both dramas that I enjoyed watching when I had loads of extra time on my hands. While the former was about two people navigating through an arranged marriage and slowly starting to fall in love, Love the Way You Are dealt with misunderstandings from the past and new beginnings, as well as a mysterious “balloon disease”. However, while watching Intense Love, I constantly found myself thinking of Love the Way You Are. The relationship dynamics between the leads in both dramas were very similar. They initially were wary of each other, both male leads were like ice cubes that gradually started to thaw out, while the female leads were more outgoing and persistent. Both dramas are hate to love and involve some degree of cohabitation between the leads. In both dramas, the female lead had a career in the spotlight that often caused her a lot of trouble and tested her ability to keep the relationship going. They also both had psychopath female antagonists that caused a lot of trouble and made viewers want to rip their hair out :P The secondary leads were also similar in both dramas. LTWYA’s Luo Yiren and Intense Love’s Wu Di were both very strong, preferring to do things themselves. They were very loyal to the people they served and hated when others got in their way. The secondary male leads were both extremely persistent, even after facing loads of rejection. In both dramas, I was a lot more interested in the secondary couples than the mains but I get that that is just a personal opinion. Both dramas are very light and fluffy, and while there is some betrayal and annoying misunderstandings, they are both very suitable to watch when wanting to kill time.
Anyways, this was a basic summary of what I found to be similar among the two dramas and is obviously over-generalized. They are two very light, fluffy dramas that give off similar vibes.

In both dramas the partners of killed people fall in love with the person who they know/believe to have killed their old love. It becomes a story of much sadness about how they supposedly betray their old loves but also how they attempt to move on from tragedy.

Similarity about the story: Both will give the healing feeling and about finding yourself and how to enjoy life with you friends or just your own company.
Similarity about the settings: The soothing and calming scenes of the countryside. Plus some parts of I, Myself was filmed in Japan.

MLs are very nice and are always the ones to help solve everyone's problems. The FLs both change quite drastically throughout the series. All of the side characters had relatively interesting stories.

Both the main characters were each other's first love. But they were separated due to past events involving their families and meet again after many years.

Another Ha Seok Jin drama with a love triangle with his brother. And the female lead is his younger brother teacher

ML and FL CHARACTER in both dramas are SIMILAR to each other.

-When Han Shangyan (ML in Go Go Squid) is computer genius, ML in 'Another Miss Oh' are sound director genius.
-Both ML are a Grumpy Boss who leads a group of boys, perfectionist, bad temper, and very cold man with very high pride.
-They also seems like rude, mean, nasty, but actually very caring, protective, romantic, responsible, and full of sweetness to the one they love.

Both FL are optimistic, cheerful, very obedient, attentive, sensible and chase the ML first.
-BOTH drama are some of the best ROM-COM DRAMA EVER ;)

-Both FL leads have 2 personalizes/2 girls one body
-Sweet and Steamy kisses
-Fluffy Romantic scenes
-Amazing chemistry

They are both amazing drama's, I highly suggest to watch The Eternal Love S1, S2 and S3 when it comes out in 2021.

Ancient Detective focuses more on crime solving compared to I've Fallen For You. It also has a bit of mild romance in it.

- Both dramas are hyperreal workplace comedies with hilarious antics that ensue
- Eccentric characters dealing with a power struggle due to corruption/politics
