“On the February 1st episode of ‘Music Bank‘, CNBLUE took home the #1 award on the K-Chart with “I’m Sorry“. While Yonghwa was making the winning speech, Girls’ Generation‘s Tiffany handed him a doll that was originally clipped to Seohyun‘s belt. Yonghwa took the doll and raised it in the air declaring his love for BOICE. After his speech, he seems to ask YoonA, “What is this?“. YoonA must have explained it to him what it was, because he nods and then starts playing around with it. Yonghwa also had a brief moment with Seohyun as she patted Yonghwa on the shoulder as the girls congratulated CNBLUE on the win.
Many fans reminisced back to their pairing on ‘We Got Married‘ and they wondered why Tiffany handed him the doll from Seohyun’s belt.
Tiffany gives him the doll at 0:43 and the Yongseo moment occurs around the 1:31 mark.”
