A friend of mine is looking for a J2 fic where they're in high school and start dating. It turns out Jared's family is really negligent and don't care about him, so Jared starts spending a lot more time with Jensen's family. There's one scene where they play basketball and Jared gets hurt and his parents can't be bothered to come check on him, so Jensen's mom takes care of him.

I hope this rings bells with someone, my friend really wants to reread this. Thanks!
