you,TCO and TDL are close friends but both of them don't know that you are secretly in love with them and that your a yandere for them

one time you were hanging out with TCO and TDL when suddenly a girl came up to them and started to talk to them and as they kept talking to the girl, the girl started to flirt with them and it made you jealous and mad so you pretended to go to the bathroom

when you were out of TCO and TDL's sight, you waited for the girl to go away from them and after a few minutes you saw the girl walking in the bathroom alone

you went in the bathroom after her while having a knife ready in your hands, you go up to the sink, next to her and the girl was busy with her makeup and then she looked at you with disgust and it annoyed you but then you attacked her with the knife and she tried to get you off her but that didn't work as you proceeded to stab her to death

after you killed her, you got rid of the body and got rid of the evidence when you were ready to go back to TCO and TDL, you saw that you still had blood on your face so you wiped it off and then went back to TCO and TDL who looked bored of waiting for you that long

TCO:"we thought you fell asleep in the bathroom, let's go, we're bored"

you nodded and the three of you started to walk somewhere
