You were going on a walk when you heard muffled crying coming from.. an alleyway? You went to investigate and found a baby in the dumpster. You were visibly angry at whoever did that

You then noticed a boy around 17 looking everywhere for something so you went to talk to him

"Mika! Oh my god.. my baby.." He took the baby from you. He turned to you "My crazy ex-girlfriend tried to kill her. I think.."
