[All] My younger brother gave me cash as a gift.

On December 26th, a documentary featuring Irene's solo activities was released on Red Velvet's official channel.

In the video, Irene revealed the recording of her new song and the filming of her music video. Irene, who revealed the snack truck she prepared for the staff while filming the music video, said, “On Monday, my mom called (the coffee truck). My mom and my younger sibling came that day, and they wrote letters for me.” She continued, “My younger sibling’s (envelope) was really thick. I was like, ‘How much did you write in the letter?’ and they put money in it. I was like, ‘What kind of money is this?’ My mom made the coffee truck for me on Monday, and my younger sibling gave me the money to make the snack truck today.”

Irene was touched by her younger sister's feelings, saying, "But I will never use it. When I used to give my mom money, she never used it. She still has the money I first gave her. I think I understand how she feels. I don't think she will use it."

However, he made everyone laugh by saying, “Dad called, but I couldn’t pick up. I’m sorry, Dad. I was so busy filming that I didn’t have the energy to pick up the phone.”

In an interview, Irene said, "My family came to the filming set for the first time and saw it. Since it's a group activity, they don't have much to see, and they probably saw the finished product when we do a concert, but it was their first time seeing the process. I thought they might be curious, so I asked them, and they said they were really curious and wanted to see it, so (they came). They saw it for quite a while. Did they see it for five hours?"

Irene “My younger brother never gives me cash gifts. I understand my mother’s feelings”

Is this a mother's heart?
