The Sleeping Monster Forest
I'm so glad I put this story on the marinated list bcus it's so good and having read all chapters, I NEED MORE. The way he's re-learning where and when he has had bad experiences or bad words, through the ML being a good guy who simply wants to love, care for, protect, and feed him, makes my heart bleed. It's so important for him, having no memories, per se, and having to re-learn everything from scratch...he met distant people who gave no good memories to counteract his horrible ones that are starting to come through.
Mismatch Guide
The ML is such a certified grade-a asshole and I hate the whole "The guide bending to the esper will" kind of trope but in this case you have an esper pulling out all stops and tricks bcus of a guide who can handle himself, constantly fights back and refuses him every chance and that's why I like the MC so much bcus he has yet to back down or yield against the esper dispute being put in difficult situations due to that set esper.
Blood Poker
I like how non-traditional this is, which guides the verse and how respectful the esper is of the guide's bodily autonomy and being clear of both their boundaries so there's no forced exchange nor forced unnecessary problems before either are ready. The MC has clear trauma and his mind vs self handles in different ways and how it shows up subconsciously which leads to a much-needed talk btw them.
