@AZMO00 There's, like, nine or ten different series by different authors, all in this Esper/Guide-verse thing. They're all really good, and so far as I've seen, all are BL. Check 'em out! You can do a search for the word "esper" I think?
Ask me about my 70+ lists, including Omegaverse, Esperverse, Dynamicverse, and Cuteness Overload!
