The Delusional Hunter in Another

Read the manhwa "The Delusional Hunter in Another" or "Otherworldly Misperception Hunter". I have a little secret: I come from a distant alien planet. After exhausting myself with endless overtime, no pay, and no days off, I reached my limit. Therefore, I decided to quit my terrible job and fled to a remote planet known as Earth. As a soul, no less! However, I ended up reincarnating into a body that had perished from starvation?! Can Gire, the alien stuck on Earth, manage to adapt without disclosing his true identity?
