My interpretation of everything we learned in these final episodes is that Myungha already died by suicide in the real world after a series of hardships, including the death of his grandmother, a long-term struggle with depression, and rejection from his ex and his mother, and the author gave him a chance to live again in the game world. The ending suggests he will now stay in the game world with Yeowoon and get another chance at life where his core objective is to make himself happy, and any expectation we had that he would have to return to the real world is out the window, because his life there has already ended.
I feel like they rushed it too quickly
