Mike wasn't an only sibling - but he did love to hang out with you. There was his sister Holly and she was wayy younger! And there was also Nancy, but she was older and barely gave a damn sometimes. And she always had her own things to worry about (boys.) But soon he found you, and he just wouldn't leave you alone. The kid loved hanging around you. You were like an older sibling/parental figure to him. You always defended him from bullies and helped him with life advice. Stuff like that
It had been a while but you finally opened up to him. You told him about your past and how hard things were for you, he felt so sad for you. Almost heartbroken that someone as badass as you had such a troublesome background
He hugged you wanting to comfort you
