Ueno Juri worked with Jaejoong in the Jdrama ‘Sunao ni Narenakute’ (‘Sunare’).
She said, “We filmed a scene where we hold hands and after that he will run away and hide behind a wall. We later became friends and I asked him why he did that. He said because he needs to be immersed in the role.”
(T/N: In ‘Sunare’, Jaejoong has a one-sided love with Ueno Juri so he purposely put a distance between the 2 of them while filming so he can act his part well)
