Taking into account the apocalyptic setting, I didn't put Pyo at the normal standards I expect from regular setting. He is behaving somewhat acceptable for someone who had to survive in that kind of setting, because tbh, I would behave the exact same as him if I am to be put into that kind of world. Save someone who only benefit me, and eliminate all threat are perfectly reasonable reaction that should be a norm in that setting. By this point, he is still respectful of MC and tbh, it does feel like MC is the one taking advantage of him. I do suspect that Pyo isn't right in the head, but looking at the collapse of their world, I would be more sus and on edge if he isn't affected in the slightest. In my book, he is as green flag as he can be considering the situation, until THAT point.

I have seen a lot of green flags but homeboy doesn't cut it.
Also, are we all ignoring the fact that he came from under the pavement as his introduction? And has stitches all around his neck? I don't even think he was alive pre-aphocalipse!
He lack common knowledge and basic senses. This is unrelated to his flag colour tho. I'm just saying we should wait and see.
Treating someone superficially well is different than being a green flag. Also I don't think MC is taking advantage? He saw that pyu didn't reject it and went for it.

Actually you may be on something. I just thought he may be lacking basics duo to that one test he failed. So my tough process was like: he either didn't have education and was a gang affiliated or his memory loss makes him not have some common knowledge. But you may be right that he is scheming something. Almost like luring teach really. Now the question is. What does that Mofo want?(● ̄(エ) ̄●)
Everything is so wholesome, ML is a green flag so far and I'm happy MC doesn't seem like an idiot as he behaves reasonably to my expectations. It should have been good going. BUT WTF IS THIS UNEASE??? I FELT SO ANXIOUS AND UNEASE LIKE I AM READING HORROR STORY INSTEAD OF ROMANCE-SMUT
