He was a kid that hated the Eight Wonder, but wanted to best her the normal way, you know, proving himself against her in a fight.
The villain he worked for, a huge bitch, took the Eight Wonder and mind-raped her, turning her into a sex slave, and gave the Eight Wonder to him for him to humiliate as he wished.
He, of course, fucked her raw, but felt bad about and tried to save her from the villain, making her escape. In the process thanks to his eyes being opened about the villain and the pity he took for the Eight Wonder, he fell for her.
Then there's the whole time travel plot where they both go to the past during their escape, where he lands back in time further than and is stranded there. When he meets her again, he's lightly older and a hero, and meets her past self, and they get together and marry, having a daughter. He eventually "dies", but in truth he just found his time-displaced Eight Wonder, that fell through time with him, and she helped he come back to the present. Now she's still in her normal age but he's an old man that lived this whole life as her husband to a younger version of herself.
