Yoo In-na mentioned IU's dating style through her YouTube channel 'Yoo In Radio.' In the video released on the 29th titled 'Complete_Couple_Campus.ver_Real_Final | IU Byun Woo-seok | Yoo In Radio S3 EP.02,' IU and Byun Woo-seok, who are co-starring in the drama '21st Century Great Madam,' appeared as guests.

On that day, the three of them played a balance game on the topic of 'Which type of lover is harder to date.' The choices were divided into 'Mindless Lover' and 'Alarm Clock Lover,' and IU chose 'Alarm Clock Lover.' IU said, "If the lover is mindless, it would be exhausting for the person preparing. I can adjust well. (A style like a 'human alarm clock') would feel cute."

In response, Yoo In-na said, "Don't be funny, IU," pointing out that although IU follows everything suggested, it is to a dangerous extent. Yoo In-na added, "IU is the type who, even when completely drained, doesn't signal it and keeps adjusting until eventually collapsing and going to the hospital." She continued, "You should rather choose number 1 (Mindless Lover). Don't collapse from exhaustion." IU replied, "Now that I hear it, maybe being a mindless lover suits me."

Previously, IU also revealed his views on love on his own YouTube channel. He once said, "If you truly love, you don't have to keep talking about love like that. Love is just something deep in the heart."

Meanwhile, IU has been in a public relationship with actor Lee Jong-suk for four years since 2022.
