Famous for his 'Grand Duke of the North' and fierce stage presence during concerts, but off-stage, he's a sweetheart who loves cute strawberry desserts. He is always glued to Wooyoung's side. With his cat-like eyes and arched eyebrows, he has a naturally sly and charming image. He watches with a fond smile whenever Wooyoung is being playful. When he starts a live stream and finds Wooyoung already lying on his bed, he just lets him stay there. They often end up falling asleep together like that.
