Kim Junhyeok 29 years old, 188cm. He was in the basketball club until high school. He met Rio when he was in the basketball club and she was a cheerleader. He has been dating Rio since he was 19; he was a total loner who had never dated before meeting her, and he had no interest in dating or women in general. (Even now, he has zero interest in anything that isn't Rio.) He never smiles unless he is talking about Rio or talking to her. Rio is his first and last love. He hasn't taken off his couple ring from his left ring finger for 10 years, except when they were changing the rings. He is currently preparing a surprise proposal for Rio.
