Kim JUNHO: ”I'm trash” - what was the self-reflection he felt = ”Growth diary of my son in his 40s”

Korean comedian Kim Junho is trying to quit smoking ahead of his upcoming marriage to Kim Jimin. Kim Junho appeared on the SBS variety show "The Growth Diary of a Forty-Something Son" broadcast on the 16th.
So, together with Kim Jung Kook and Kim Seung Soo, they actively tried to break free from their respective "addictions." Kim Junho said he was going to quit smoking when he proposed to Kim Jimin.
They declared that they would keep their promise. They decided to return all of the belongings they had brought with them before entering the room, and Kim Junho surprised and laughed at the same time with the precision of hiding his e-cigarette in his trousers.
Kim Junho, who was put into a 1.5 pyeong cell, had nothing to do but sit still and stare blankly. He also farted while looking at the notes written on the desk, and soon fell asleep.
Kim Junho woke up and was playing with a box when Kim Jung Kook in the next room complained that he was too noisy and they started talking through the wall.
Kim JUNHO used the situation of being locked in a room as an excuse to call Kim Jung Kook "Hey, lump" and "mosquito" and to "Hit me. Hit me," provoking Kim Jung Kook and throwing a laugh bomb.
After a while, the broadcast of 108 bows was aired, and Kim Junho made everyone laugh by his realistic appearance of being unable to hold in a fart while bowing.
"It's really hard," he said, complaining about the pain, then immediately curled up in his futon and fell asleep, showing off his low-quality physical strength. The bell finally rang to signal the time for the long-awaited meal, and Kim JUNHO was eating his morning meal.
When the simple meal of one potato, one apple, and one drink was served, he couldn't hide his confusion and asked, "Hey, do you have something like a set meal?" Then, Kim Jo, who was in the next room,
He called Nguk and showed up at the catering counter with Kim Seung Soo and suggested a "247 Game" where the prize was to "take all the sweet potatoes". He fought closely until the end, but lost the game and had nothing left.
However, Kim Jung Kook hid in his room to not hand over the sweet potato, and cursed him saying that if he did not hand over the sweet potato, they would divorce again.
When he showered leaves on her, she threw them far away in a nasty manner, showing her anger. Kim JUNHO's provocation did not end there. He took out chocolates he had hidden in his socks and
He called Kim Jung Kook and Kim Seung Soo and said, "I'll give chocolate to the person who is good at self-reflection." Kim JUNHO, who showed the example first, promised to quit smoking with Kim JIMIN,
He then said he bought two more e-cigarettes and laughed at himself, saying, "I'm trash." "The Diary of a Son's Growth" airs every Sunday at 9:05 p.m. on SBS in Korea.
