yandere x y/n

what's happening?

when you told the twins that, turns out echo heard you and was happy but they said it weirdly "thank you so much for picking me over those people i would kill you if you chose them!" it was kinda weird but they might've thought it sounded different in their mind! yn thinks : "yeah in their mind! i hope it wasn't meant literally or i could've died if i didn't choose echo.." you shook your head "no..! they would never do such a thing..! i hope..." as y/n walks with echo they grab a drink! but someone starts staring at y/n you get uncomfortable.. echo sees the person and looks at you later tonight you look at the news "oh..? whats this..? a murder.? wait!! THAT WAS THE DUDE YOU WAS STARING AT ME!" you told yourself it might just be a coincidence, a few month later someone sends you a box of chocolates, a card, and.. a.. KNIFE? WITH BLOOD ON IT? you open the letter reading out "i.. i.. was the one who killed the man.. y/n IM BADLY IN LOVE WITH YOU" you drop the knife and the card. who did such a thing..? and it was all for me..? what.. why.. how.. you had so many questions but you had to pull yourself together
