Both are NA PD shows, Earth Arcade is pretty much a -sister- counterpart to the NJTTW show, who has 9 seasons and it's a hugely popular show.

Kai reminds me a lot of one of the main characters here. These movies have similar themes/pyschological aspects and they're both very good

In Both dramas the leads are acquainted in the past( L&P leads are lovers in college but MLH the ML has an unrequited love since childhood)
My little happiness is sweet and fun, while lighter and princess is a little dark and thorough
The leads are reunited while they are older and become colleagues

Both dramas are about young lovers who are separated because of life mishaps but keep loving each other despite the separation
In both dramas the leads meet again when they are adults and reconcile
The leads in both have somewhat complicated and heavy pasts

Both dramas are set during school/college days
The leads have a love-hate relationship at first that turns into romance
The leads are separated due to mishaps showing up but keep loving each other and meet up again in the future
The characters in both have heavy baggages from their past and have been through trauma

-Main couple in both dramas were complete opposites and were at odds with each other in the beginning, with the Male Lead secretly holding a crush on the Female Lead.
-Both Male Leads are smart. One being a born genius with high IQ/photographic memory and one is a jack of all trades. Both decide to lay low in life being freelancers and unemployed due to their own reasons.
-Both Female Leads open their own practice to realize their dreams. Both have a strong sense of justice, are honest and straightforward. Once they realized their feelings, they waste no time to confess.
-Once Main Leads officially become couples, they turn into sweet, fuzzy, cheesy and cringey couples where bystanders gets sick of how lovey dovey they are to each other. Which in it itself was hilarious to watch but also give you a warm and happy feelings.

Both are romantic comedy at its finest.

Both dramas revolve around school and college days
The leads fall in love while at school
The leads are separated due to mishaps and are later reunited
Past love cannot be forgotten sort of dramas
Both give off warm vibes

Both are mystery/thrillers that have a heavy bromance focus (Blind is very familial focused). As I was watching Blind it felt very reminicent of when I watched Beyond Evil for the first time. Especially with trying to figure out who the culprit is and trying to put all of the pieces of the puzzle together. Both have a lot of twists and turns along the way that will blow your mind.

Both FL have a manipulative and violence Boyfriends Both are good drama/movie
Weak FL
Both plot about society and mental health
Both not really similar in plot but I kinda have a feeling similar from both

Thong Nuer Kao is similar to Krong Karm :
-Same directors
-Same young ML
-Karma topic and retribution

They're both Japanese BL series with supernatural stories.
Both are very fun and entertaining to watch.
2 of the most underrated Japanese BLs if you ask me!

Neung Nai Suang is similar to Padiwarada :
-same hisotrical period 1950-1960
-Orphan femal lead

Preety much identical, has a cursed lead who is not happy about his meaningless existence, a cheeky female lead, decent comedy but the 2nd romance takes the cake for me than the main one
