Being extra happy and touchy in their FMs or concerts
Both did other fan meetings with other partners but I never saw them that out of their mind happy. I still remember a fan account from a star angel that went to that meeting . The one who made that flower bouquet for Shin Hye and she threw it to the stage for PSH but sadly it fell away from her and went unnoticed. Then suddenly JKS saw it on the ground and just like it's his fate to bring Shin Hye the things meant for her even when they fell short of reaching her , he brought them to PSH's own hands with style! Kneeling on one knee he gave her the flowers. Isn't it just wonderful? He didn't know it was meant for PSH but he gave it to her anyway

The star angle was so happy.
Tokyo Dome concert , JKS dream since high school came true and he called it the beginning and the only female to grace one of the most important mile stones in his career was no one but PSH. They hugged back stage , they sang together and they even leaned on each other on stage with huge smile and happiness
Bold declarations!!
PSH talking about how much JKS's mother loves her and wants to be her daughter in law while holding Suk hand Lol I remember how suk couldn't sit still in this interview because of how happy he is. He even went along to steal the camera and film Shin Hye declaring how beautiful she is

Say Hello to Mother in law Lol! Sukkie! You're too obvious! Sukkie says " I love you " to all his friends and family even to the male ones but he never called any female's mother " Mother in law " ..... well .... except PSH

very bold indeed!
JKS's 20th anniversary dinner JKS declares his mother will only allow him to marry someone three years younger than him and in the year of the horse. I wonder who that might be Lol! He keeps repeating every year. If he has any girlfriend she would hate him and his mother for insisting like that.
Another bold declaration in PSH's FM last year! " It has always been my desire , PSH , will you marry me? .... Lol Joking! " annnnnnnnnnnnnnnnnnnnnnnnnnnnnd he hits again! Never did he say will you marry me to anyone! Only Shin Hye! Again bringing his mother . JKS are you sure you're not using your mother's words to get what you want across?
