For me, the only happy ending that I can see is NK realizing how powerful he can be in terms of influencing SH. The fact that he can stop or distract SH from hurting the learned sir is a proof, i think. And even though SH is using the sir as a leverage for NK to stay and have sex with him but once NK realized that the sir is just using him and doesnt even care about him, my theory is that NK will use SH to get revenge on the sir.
Bottom line is that NK will be a badass bitch and SH will blindly follow him because he is addicted to NK. ╮( ̄▽ ̄)╭
that Jeezwah asking how NK tastes, bruh he is more than that. SH likes NK’s drawings first before his body. He is NK’s fanboy (╬ ̄皿 ̄)凸
