Based on some spoilers, it's related to some circumstances surrounding the MC that gets revealed in a future arc and the team leader's identity. I'm not exactly sure how they're connected but it's bound to be shocking.
That’s kind of what I was thinking. Since team leader asked a weird question when they first met (like if he could see, idk remember the exact wording).
Also the fact the MC has red in his eyes, might just be part of his design but I feel it may have importance with team leader having red eyes and the fact MC said something about the color red recently.
I feel that little inner thought the researcher had about MC and Team Lead look potentially related is important. I’m curious what that’s about.
