"Okay," Zhao Sean agreed readily.
He had seen this coming even before Leo finished telling him his story. He figures that he'll have to do the same – recount his story to Leo after Zhao Sean had managed to coax Leo into telling him what happened. Leo deserves to know at least, he thinks. He deserves the same respect and courtesy that he had given Zhao Sean. Zhao Sean knows how big of a step this is for Leo–for him to tell, but he still took the risk and leaped ahead to spill everything to Zhao Sean. Zhao Sean is still practically a stranger.
And Zhao Sean had felt so honored and grateful that Leo had opened up to him. It must have taken Leo a lot of courage to open up.
