On the March 24 broadcast of MBC's 'I Live Alone', BTOB's Changsub appeared as a guest and shared his single lifestyle with viewers.

On this day, Changsub showcased the interior of his house for the first time on a TV broadcast, revealing his simple and casual preferences. 

It turned out, on days when he's not an idol on stage, Changsub mostly spends his days as "Guri's Dad". Guri is Changsub's 1-year old beagle. 

First, as soon as he woke up in the morning, Changsub started off his day by feeding Guri kibble, warming the dried pieces up with his breath so that Guri could chew enjoy his breakfast more. Afterward, the idol spent around 2 hours playing with Guri in the living room, chasing the dog around or pushing and pulling on a chew toy. 

Next, Changsub dropped Guri off at puppy school, then went to the gym. He finished up his routine at the gym quickly and grabbed donkatsu for lunch, before going shopping for Guri's clothes. A quick shopping trip later, the BTOB member arrived at the Han river, a blanket spread out in the back of his Jeep, and passed the rest of his afternoon with a stack of manga. Here, Changsub observed, "I used to never go outside. But thanks to Guri, there's a reason for me to go out. I just find ways to pass my time while waiting to pick Guri up."

Finally, Changsub bought the envy of the 'I Live Alone' cast members by revealing that a sauna was located on the lower level below his apartment complex, and headed inside to wind down for the day in the heat. 

What do you think of BTOB Changsub's simple and quiet lifestyle?
