In November 2020, Yoo appeared on the variety show You Quiz on the Block and gushed on various topics, ranging from his projects, characters to poems. One subject that captured everyone's attention was his statements regarding his personality.
The interview's host asked Yoo how he would reply if his girlfriend asked him how much he loved her. "Oh, yeah. I love you," Yoo boringly replied to the question before clarifying his personality would reflect on the answer.
He added he wouldn't be able to overcome his shyness and look at his supposed girlfriend.
After the reply, Yoo mentioned he found dating and relationships awkward, explaining he wasn't the type of guy women liked. "I don't think I'm the kind of man who's bold in front of love," the Squid Game actor added.
