'Who loves me?' Is grammatically correct.

Hi Laku. I'm not specialist in English, but we only have to use "do/does" in question, before pronouns (I, he/she/it, you, etc), not a verb. It's like "what happened"? Also there is no "do/does" because there is no "person" in the sentence. So, "Who loves me" is correct" and the other one is wrong. Am I clear?
