You know something stars, I have great faith in JGS and PSH getting together one day.
First off, they have great chemistry, and both are going to be starring in dramas with attractive roles of the opposite sex. Its only natural that JGS will be jealous of the male lead of Hayate, and PSH of the female lead of Mary Stayed out all night.
Second, they used to live close and could see each other all the time, but now they will be living far apart!!!! Absence makes the heart grow fonder- fact
Third, I have experienced myself falling in love with my best friend- and it took 3 years for us to get together

there is PLENTY of time for JGS and PSH to go out ^^
Finally, with all the evidence I've seen from the Tawain concert- the firm hug in the reinactment scene, the flowers, the hand holding at the end- JGS really wants to be close with PSH. Plus, PSH was looking amazing- the long, curly hair and slightly chubby cheeks- his perfect type for sure ;P Plus, who can resist PSH after that Beyonce dance??? Even a guy she barely knows was calling it sexy on TV-- JGS can't be oblivious to that
Keep the faith, hwaiting!!
