Ever since you saw Himiko in school you fell in love! Do the only reasonable thing to do was stalk her!

Overtime Himiko realised she said being watched

she learnt it was you and his Yandere for her you were and she…

…liked…it…

she wanted you to feel that way for her…infact overtime she herself started crushing on you

she walks home from school waiting for you to start stalking her

“Any moment now…”

she hasn’t told you that she knows about you so it’s a complete secret that she knows you stalk her
