Ummm... The only "happy ending" I see here is Aizawa being one of these ghost of someone who is in coma. I don't see that's the case here since they said she was dead already, unless her family and/or company decided to spread the rumor because reasons... Worst scenario, MC kills herself to be with her. I really hope is not that-
Now you've reminded me of a comic where this abusive girlfriend acts all cutesy and innocent to her lover who can see her after (they killed her), which makes the lover kill themselves out of guilt and out of belief that once they die, the girl will be free as they thought they were the one keeping her there. Well, they were.. But definitely in a bad grudge way..
Oh I believe that's "I was wrong" by Hakuri. It's a good story if you're into Yanderes, it's het however. The Author did write a Yuri Yandere too, I'm not sure if it's here but it's "You're still in a bird cage."
President is kinda piquing my interest.
But my girl Sayo deserve love too, I feel so sad seeing her hold herself back knowing well that Mei only sees people as friends. Yet she still loves her deeply. I WANT MY SAYO ENDING.
