let me cuddle you (just a tiny bit, please) (слэш)

Harry's back at Hogwarts the summer after War, helping with the rebuild. Or, at least that's what he tells everyone. The truth is that he has no purpose anymore and he's confused and numb and maybe being back at the one place he's called home will...help? And then he sees Snape, and the man looks even more lost than Harry is, and Harry feels something again.
