This reminds me of all cheating men must die but like,
The first two turned gay for each other,
The other one has a love interest and is a masochist,
And the Recent one has a crush on his...cousin?

I'll reply this in every comment comparing the two.
Look... first of all... this is just ONE ACR of a novel. And the comic from it makes no justice to the novel. It's name is Cannon fodder records of counterattacks. Just in case you want to check it out. But you should really read the novel.
Now... let's talk about the similarities and differences between them ok?
Cmmd and Cfrc are similar in 2 points only: they are quick transmigration (qt) and are not romance (usually qt romance has one guy they meet in every world that don't keep their memory but follows the mc around the many worlds and they end up together) that's it.
That's the only similarities. Now for the differences.
Su Luxia is obviously not a "normal person" from the start, it's clear even on the side story about her 1st mission. Ning Shu is a 27yo who died after spending most of her life in a hospital bed. So... she is not OP at all... if anything she is worse than normal people. No knowledge, no relationship experience, no high stats, nothing. So in the first words she has it real hard and this arc is a challenge arc so she can be considered a normal host instead os a fricking noobie.
NS's system is not helpful AT ALL as you've saw unlike SL's bamboo rat he does nothing for her and actually expected her to not even live enough to get over being a noobie. That's how weak she starts as. No system store, no help finding the targets location, no accompanying her through the worlds. She has almost no help from him at all in almost all the worlds she goes.
Cmmd is about a OP mc abusing scum and bettering that body's life. Cfrc is about a WEAK mc getting stronger TO SURVIVE and completing the body's wishes.
Don't get me wrong, I absolutely love cheating men must die. But in regards of character development and world building Cannon fodder wins. Maybe because it's a novel with more than 4k chapters and not only a comic.
The novel is way more slow paced than cmmd... and as I said, besides those 2 points (and getting revenge on others) they are not really similar.
Also... Ning Shu can be more "cruel" than Luxia sometimes... xD
... they make people in a relationship feel single..
That's me, the person in a relationship
I am single ant this manga makes me singel 100000.... #crycry
