Return of Boros (Currently being Rewritten)

After Saitama faced off against Boros, he unleashed his Serious Punch against Boros's Collapsing Star Roaring Cannon. However, instead of killing Boros, what if he survived? What if he was weakened severely by the Serious punch and needed somewhere to rest and recover? He rests in the house of a human girl in order to heal, and the girl doesn't know what to think of this. Will Boros go after Saitama again to see if the prophecy was to fight him, or will he set his sights on a certain Hero Hunter?
