Both feature:
- young female leads who are trying to survive against enemies who are trying to kill them
-dark killer themes
-kick ass female action
-strong female empowerment

The stories are completely different, but the message/theme is somewhat similar

Similar concept: Contestants gather together in one house to battle it out with intense games. Smarts, Skills, and alliance strategies all come to play. Backstabbing is a must. Bloody game has a few more twists which was more entertaining.

Both are about family and life's hardships. The sacrifices families have to make to survive in this world.

Both shows involve teams that form a bond through their shared occupation and go through survival games that include physicality, strategy, and teamwork. The games aren't the same, but the growth and spirit of the members have a similar feel.

Both feature the key members of the Wooga Squad going on a trip and hanging out and enjoying each other's company.

Both have MLs who are uncouth and follow the FLs around like a loyal puppy and who are also possessive of the FL
Both have FLs who are a bit aloof and treat the ML like a puppy

Both dramas have leads that are best friends, mean everything to each other and have a close bond.
Both dramas have the ML liking the FL and trying to keep those feelings in check
Both dramas have a turning point when they cross the line into possible lovers

The slow and steady quiet burn for the FL from the ML are kind of similar. How they seek to be quietly near the FL. That's about all that's similar, but I find that kind of ML with that kind of quiet burn is hard to find. It's the vibe that's similar and not the actual story or character.

The stories and styles are not the same, but I feel like if you like Our Blues, you may also like Go Ahead. Both address the complex emotional baggage that comes with family or lack of.

Go Ahead focuses more on the romance though and there are clear leads, but both are well done family dramas.

FLs are both feisty
MLs don't know how to handle the FLs and get flustered
MLs gets jealous easily
Both leads fall for each other pretty quickly
The chemistry in both are so cute
Both have a similar feel even though the story is different
Both are short dramas
Both are a light easy watch

Both are military survival competitions, although the concept is a little different
Both have very similar drills/games/missions
I think The Soldiers was actually spun off from the Iron Squad because of it's success.
I think Iron Squad is much better imo as you get to know the contestants more, there's MC panelists, and more heart, but if you're in the mood for more military competitions, then try the Soldiers.

Both have Kim Seul Gi & Ahn Hyo Seop
Both are a short mini romcom
Both are lighthearted, silly, cute & funny
