I don't want to hype this manga too much but so far it's a 9 (might change my rating depending on the ending). I have tried reading the author's other famous work Kaguya-sama and I didn't care for the female lead/rom-com aspect. If you go into this expecting wholesome comedic romance you are in the wrong place. This manga has a good balance of plot, tension, cute moments to keep you reading. On top of that you've great characters with inferiority complex, love, obsession and insanity. If you like thriller idol horror manga I recommend.
