I love this! I think main character has autism (the seme), and I love how they developed the relationship without making his acts as something "bad" but rather a little socially uncomfortable and that you can get use to it. Also it's not all about "don't change", it's a message about changing for the best and finding people who can understand even in this extreme situation when you just can't understand social standards. I love it!
