One day I will go through properly and make a more comprehensive list but RIGHT NOW, OFF THE TOP OF MY HEAD, I PICK THESE THREE. IN CHRONOLOGICAL ORDER.
NUMBER ONE: OUTO MISCOMMUNICATIONS
In which Kurogane is trying to say with words just what his actions mean and it doesn’t quite work.
Ie, through a complicated mix of Kurogane not wording it very well in the first place, Fai having no sense of self worth, and Fai also failing to ever consider that other people could like him any more than he likes himself (which is not at all), it’s made clear that neither of them really know how the other works at their core but the reader gets to see it all regardless.
NUMBER TWO: DRUNK TIMES IN SHARA
Where, among other things, Fai’s starting to realise that his falseness just straight up doesn’t work on Kurogane. Kurogane sees more of Fai than anyone else and yet despite that he’s still here, and Fai doesn’t quite know what to do with that information.
AND NUMBER THREE: THE SIX MONTHS OF GAY
Which, admittedly, was all off screen. BUT COME ON.
SIX MONTHS of Fai and Kurogane alone together, being forced to communicate without words, and becoming an inseparable battle duo in the process. There is a lot in there and I adore all of it.
