I doubt Aoi is his childhood friend, he met her when he was a working adult and refers to her as a kid sister.

Aois reson for killing him is probably fairly simple. She was a stalker and the target of her stalking brought another woman home. While Rou says that he had slept with his coworker a couple of times it was probably not at his place, seeing him bring someone else home, smashed, might have shattered her image of him and tipped her to the "If I can't have you no one will" mentality.
