Harry wasn't as unaffected by the war as he thought and returns home to Hogwarts when being an Auror is more than he can handle. Harry and Severus fall quickly for each other, but being in a relationship with Severus Snape is far different than any relationship Harry's been in before and he introduces Harry to Domestic Discipline. Severus will provide loving structure to their relationship and consequences for Harry when he breaks Severus's rules. Harry's quite surprised to find out how much he needed this.
Remus becomes his "cousin" Orion Lupin in order to guard Harry. Harry becomes close to his new classmate.
