This is basically a F a round and find out moment or a "don't ask for smoke if you can't handle it" this isn't child games which is the point if it was just cheating that would be one thing but she activity allowed the MC to face some of the worst crap to the point he wanted to end himself. People like this earn what they get and
kill herself as with is just a cowards way out and will and always be a selfish thing to do because of the damage it does to the people who know the person and those around them.
It was good Ai had her watched and confronted her, she didn't even DO IT because she gave a fuck about her, only the DEVESTATION of what will happen to MC if she did kill herself, it took a bit before she even REALIZED when he told her to STOP TALKING that he was TRYING to protect the "innocent her he grew up with" in his memory AND not have it SPOILED by "the rotten POS she ACTUALLY was AND CHOSE TO BE EVEN AFTER EVERYONE FROM HIS FAMILY, TO HER MOTHER, TO HIM! EVERYONE tried to PREVENT!" Sucks that it took one "fuckboi" and taking an eye off her for a SECOND for her to fall this far! She was ALWAYS a weak Parasite, who even DELUDED herself into thinking she could STILL HAVE HER HAPPY ENDING! that by the suicide attempt, she's ALREADY been found out and ALL HER SUPPORT is gone, her remaining friends no longer trust or want ANYTHING to do with her, and her supporters turned from bullying Aono...TO BULLYING HER And yet she STILL needed Ai to spell it out for her what she has ALWAYS BEEN, I think at THIS POINT is when even her "inner woman" turned on her, because it was ALWAYS her "real feelings" and her real feelings couldn't understand WHY she was this delusional, stupid and narcissistic NOT MY FAULT!
