Honestly, one thing that really pisses me off about half the characters in this story is the same thing that pisses me of in half of all the stories i consume, people don't just fuckin talk their issues out properly, if at all, like fuck, if i was Akira i'd be sitting her down and saying something like "ok, ffs Ami, you NEED to stop worrying about losing me, i'm never ever going to drop you, you have me for life, that doesn't mean you have me all to yourself, i want to hang out with your classmates, i want to hang out with my adult friends, but you will always be dear to me, you'll never have to move out and make a life for yourself without me so stop with all this possessive stalker crap, that's the sort of shit that could land you in an insane asylum and i don't want to lose you to that so just chill, just chill and we can be together as we have been for as long as we live."
Now, i recognise that would be absurd to hear coming from his lips but that seems to encapsulate his thoughts and feeling pretty well and full informs Ami of her options and what to do to keep her happy bubble safe and what will happen if she goes to far this way or that way. I'm not saying it'd work, but at least there'd be none of this obfuscated masking shit, if she rejects it then it'd be good if she could be just as bluntly honest in return, let rip on Sensei and leave him fully informed on wtf she's going through.
Have em go back and forth at each other, get it ALL out and deal with it and then maybe, just maybe, shit could improve and work in a more healthy way.
But i guess that'd make for a boring game and it's why i am a reader, not a writer.
