So far, yeah. His goal is to control. He originally raped Poyem anytime he found him and tried breaking his spirits to keep him, then he changed his approach. Han became the "puppeteer" in Poyem's life to keep and depend on him alone.
Poyem, however, suspects the sudden change but is too soft-hearted to piece it together. The 3rd guy is also after Poyem as well. However, he also (allegedly) pity Poyem.
That's all I know so far.

If Pyoem will start to realize
But even if he did, will he escape? I wonder if it will be like that "Secret Alliance" on Lehzin. The one where the guy stalks the girl who looks like a guy but dressing up as a girl, but he doesn't get the girl, someone else does.
