CNBLUE's Yonghwa gave his 'wife' a piggyback ride for the very first time on this week's "We Got Married." Yonghwa and SNSD's Seohyun have been showing fast progress in their relationship lately, as demonstrated by their brave attempts at skinship. For this week's episode, the couple brainstormed together to compose lyrics for their 'banmal' (informal) song. Taking a break, the two walked over to the Han River, where they bet on the results of a short basketball game; it was agreed that the loser had to give the winner a piggyback ride. Yonghwa ended up losing the match, and piggybacked Seohyun all the way home. Feeling self-conscious, Seohyun asked, "Aren't I heavy?"  Although Yonghwa jokingly complained that she was "really heavy," he repeatedly asked her to "hold on tight" and never lost his smile. In a separate interview, Yonghwa stated, "Girls are so coy," and burst out into laughter as he reminisced over the moment. Seohyun gave a shy apologetic smile towards the camera and stated, "I'm heavy and my bag was heavy, which created a combined effect." Source + Photos: Asia Economy, Newsen
