Actor Lee Jong-hyuk's youngest son and the adorable Jun-soo from 'Where Are We Going, Dad?' has returned as a handsome young man.

On the 23rd, the SBS variety show 'My Little Old Boy' featured the meeting of Lee Jong-hyuk and his son Lee Jun-soo, along with Lee Sang-min and Lim Won-hee.

Earlier, Jun-soo, who appeared on tvN's 'You Quiz on the Block' in May 2021, had entered the scene with a significantly fuller appearance. When asked about his height during his 15-year-old middle school days, Jun-soo said, "I am over 170cm," and Jo Se-ho expressed envy, noting, "You’re in the second year of middle school but I really wish I had grown this much too." The transformation from the playful 'Nation's Nephew 7-year-old Jun-soo' loved by everyone garnered much attention.

On this day, Jun-soo amazed viewers once again with his unbelievable growth.

Taking after his dad and mom, tall Jun-soo reached a height of 194cm, and he noted, "I grew a lot when transitioning from middle school to high school." He expressed, "Honestly, I want to reduce my height a bit. I wish I was around 187cm."

Additionally, compared to his appearance on 'You Quiz on the Block', Jun-soo showcased his handsome looks after losing a significant amount of weight. He stated, "I have been dieting. My highest weight was 109kg, but since I grew taller, I am now 88kg." Having lost 21kg in the meantime, Jun-soo revealed, "I ate only one meal a day while following a diet plan."

He also mentioned that he practiced handstands a lot while dieting, adding, "I exercised a lot to do handstands," and he showcased his slimmer physique by successfully performing a handstand after some stretching.

When asked which member of 'Where Are We Going, Dad?' he was closest to, he answered, "I am closest to Yoon-ho." Yoon-ho, the only son of Yoon Min-soo, has recently gained attention for being accepted into a prestigious university in the U.S. There was also a question asking whether there was any comparison between the two. In response, Jun-soo said, "I don’t know about the comparison. I don’t really care. I’m not good at studying."

He continued with a laugh, saying, "I originally planned to give up studying," and when asked, "Who do you resemble more, your mom or dad?" he confidently replied, "Dad."

Currently, Jun-soo is attending Goyang Art High School's acting department, and his older brother Tak-soo also aims to be an actor, having entered Dongguk University's Department of Theater. There are expectations to see all three sons actively participating in acting.

Jun-soo also shared his first dating experience. When asked, "Did you have a girlfriend?" he revealed, "I have met someone before," drawing interest. His father Lee Jong-hyuk was surprised to hear that his son had a girlfriend in middle school. Jun-soo mentioned, "We held hands and hugged," referring to physical affection, and Lee Jong-hyuk was humorously shocked, asking, "Hug?"
