TL;DR: The juice is simply not worth the squeeze. Wasted potential.
Summary: (spoiler marked)
My inner dialogue for the majority of the story: OMG I love this!! Absolutely iconic yandere!! 5/5 stars!!
My inner dialogue at the first plot twist: Okay.. seems a bit forced and confusing, but I'm with it still. 4.5/5.
Second plot twist: Wtf is happening?? How will the mangaka make this make sense?? Tentative 4/5 stars
Ending: WHAT DID I JUST READ??? HELLO??? 3/5 IM SO CONFUUUUSED
**SPOILER BELOW**
Final thoughts: IT WAS ALL A DREAM??? WHY DID I WASTE MY TIME ON THIS??? SUCH AN ANNOYING CLICHE ENDING, AND WAY TOO CONVOLUTED TO MAKE UP FOR IT!!! Not even any smexy scenes smh 1/5, NOT WORTH IT!!!
