I love your books so much but Actually, there are a lot of stuff you have to change it about thinking of Yanderes' personalities!
They are physiopath because they are extremely jealous on her bf/lover !!!!
So do you remember in the queen of Yandere in Mirai Nikki
Yuno said ( if you will be satisfied by killing me, then kill me) and always she says ( I love you yukkii) so you have to do this (After killing Akari-kun, after killing my safer...after killing my dream..I said my life has no meanings now...I just returned to the old life I was be...I had a very lonely life..so..I don't want to live anymore..I don't want to live with no meanings ....all of my life had a goal is to safe Akari-kun from those bitches...from everybody who wants to seal him from me...he is just mine....JUST MINE...but now...I lost him....I..I..lost him...all..of..my..life..w..was about him..but now..he died I cannot imagine how did I do it... My ... My.. I killed my last chance to find a good life in this universe ... In this world... I just closed the last door... I back on my word... I didn't even save him from me.. i can't bear leaving this life ... No I can't.. he meant everything to me.. I was dumb .. I was so dumb.. i'm dumb... I'm dumb.. I can't live this life I hate this world.. I hate this universe.. I hate all of the people in this life.. I hate .. I hate .. I just hate... I hate all of my life... I hate whole of my life.. I didn't even have a normal life.. I didn't have a normal family.. I didn't have a normal sister.. all of my family were killed... Why does this happen to me... What did I do... Oh my Akari-kun... Your dead body is so warm eventhough you died... Revenge took over me.. and I wanted to make you suffer.. I'm sorry... I'm sorry...I'm so..sorry...I'm s..sorry... This the only word I can say ... *Sorry*.. please forgive me..
Then Mikari puts the knife into her chest and put Akari-kun's knife into her heart
Yes! This how must it be!
