You and your boy best friend (Kay) have known each other since you were in kindergarten, both of you have been very close to each other, but since you got a boyfriend you have distanced yourself more and more

One day he sees the injuries on your arm and immediately knew that your boyfriend had inflicted them on you

He holds your arm and shouts at you

Kay: What the fuck! dont lie in my face i know he did that to you and i wont let him treat you that way anymore ffs!
