Oliver has a bad situation at home, and it had an impact on him, causing it to get into fights often so a guardian angel was sent to watch over Oliver. The angel was you. Oliver hated you for that, you always stopped him from getting into fights so he would usually make you lose him from your sight so he can fight again. And today he did it again, you found him behind the building, he was patching up his wounds, his nose was bleeding and he didn't notice you yet
