Actor Ahn Jae Hyun, ”Relieves physical energy by doing lower body exercises and climbing the stairs to the 20th floor”... Confused by the ”1+1” at the convenience store = ”The happy life of a single man”

Actor Ahn Jae Hyun was seen struggling to go up and down the stairs due to elevator construction.
In the episode "I Live Alone," Ahn Jae Hyun stumbles around with a pile of recyclable garbage. "It's because I can't see ahead," Ahn Jae Hyun says. Im Woo Il responds, "Hey,
"I want to go there all at once," he said. Ahn Jae Hyun then aroused curiosity by going down the stairs instead of using the elevator.
Ahn Jae Hyun said, "The time has finally come.
Elevator construction is underway in the apartment building where I live.
My house is on the 20th floor. The elevator construction started yesterday and will continue for the next month. The notice has been up since last year.
I was mentally prepared from that time on," she said, surprising everyone. Ahn Jae Hyun responded, "Exercise has always been a part of my life recently.
"I'm definitely going to work out. I need to work out to maintain a healthy body," he said as he arrived at the gym.
Ahn Jae Hyun has joined hands with his gym trainer and begun some serious exercise.
Ahn Jae Hyun said, "I naturally thought I wouldn't be doing any lower body exercises today. But construction work started today.
"If I do the lower body today, it makes sense to do the other month, so I've decided to do the lower body."
And Ahn Jae Hyun gained confidence from lower body exercise. Ahn Jae Hyun stopped by a convenience store to buy some detergent because he ran out.
She picked out a small item. However, the fact that it was "1+1" made Ahn Jae Hyun say, "This one? Can I have one more?" and he had to carry it up the stairs.
As Ahn Jae Hyun sat on a bench in front of the house, Key (SHINee) suggested, "How about you try living here for a while?", causing everyone to erupt in laughter.
Next, Ahn Jae Hyun started wrapping snacks he had bought at a convenience store. Ahn Jae Hyun said, "When I got off the bus, I noticed that there were a lot of elderly people moving around.
"The children and others were having a harder time moving than I was. I thought that if they had something sweet to eat, they would have more energy. I made a snack bag for each chair," he explained.
Ahn Jae Hyun discovered his delivery on the first floor and lamented, "Another unexpected delivery."
Ahn Jae Hyun explained, "It's kimchi that my friends send me periodically."
Next, Ahn Jae Hyun struggled to carry detergent and kimchi up the stairs. Ahn Jae Hyun said, "If other people are really struggling, I can't think of anything.
"I only had one thing in mind: my front door. I really wanted to see that front door," he said, explaining his feelings at the time.
