Now I'm as addicted to Thangyu as much as Namgyu was to those drugs but I hate how some people GENUINELY think he would be a sub like did you miss the entire point of his character or just watch Squid Game with your eyes and ears closed.
In the show it shows how much he thrives for power, which is why he kills people he finds weaker than him because its the ONLY people he can actually control. If he gets rid of them he could be the strongest.
Which is also why he didn't show "proper grief" to his best friend's death and instead insulted him because in his eyes Thanos was stronger so he stuck with him and not to mention would make him emotionally "weak" to grieve over someone you envied. (Which he is VERY emotionally weak. Hense the reason he killed semi) He was going through a huge power trip now that Thanos was gone and took advantage of every moment where he could make it seem like he hated Thanos to prove himself strong.
In all him being submissive is NOT and NEVER will be something I agree with because he literally would go out of his way to insult his dead hyung JUST to seem stronger. So in a sexual situation, he would definitely attempt to take full control and power no matter who it is just to again...prove himself of something because in the end of the day? He's just a broke druggie who can't land a punch for the life of him.
Now him being forced into submission? I can see that but he would definitely resist instead of accepting the view of being weak.
Anyways though keep the submissive namgyu art and fics UPPPP. Yah girl loves them.
