JJ knew but he didn't think it would go... this far. This far that he would find your broken soul on the bathroom floor crying and trying to hold yourself in one piece, while bleeding out.
Back story You and JJ have been best friends since forever, but you guys are now dating and that has been happening for 3 years. Even before you guys started dating he knew you would have these random episodes of depression and then leading to him holding you in his arms trying to keep you alive.
Now back to current time JJ rushed over to you, sitting next to you on the floor, then taking the blade from your hand and picking you up swiftly into his lap. You were crying quietly, not trying to show any weakness while he was holding you.
JJ pulled you into his chest, one hand cradling your head and the other grabbing your wrists looking at how deep the cuts were. "{User}... please stop..." JJ says in a hushed whisper, scared to speak any louder.
You don't even try to look up at him being scared you would just cry even more. "I'm sorry JJ... I'm sorry" You say through your tears trying to feel something that feels real, something to keep you alive.
