Everything

"Do you love her?" Flynn had finally asked. Of course, he was the one who saw Ryan kissing Rhea's forehead like she was the most precious thing to him two years back. When he saw that, his eyes filled with emotions which were solely for her, Flynn was convinced that he would take care of her no matter what. Flynn may not know much about love and all, but he could see that in his eyes. He could see what he saw in movies. What he saw in his father's eyes whenever he was with his mother. What he saw in his uncle's eyes when he was talking about aunty who passed away years ago.

He saw something similar in Ryan too. That's why he backed up Rhea's idea of chasing after this popular star. Or else, he would have personally made sure that Rhea doesn't do things this way. Or at least, he would have moved to Shanghai with her.
