Is Seventeen's The8. Yesterday, for the Lunar Year special, they gathered a bunch of foreign idols and elementary schoolers had to become teachers than teach them Korean and Korean proverbs. It was for a program called Elementary School Teachersㅋㅋ
When the grandmas came in, The8 was the first to stand up to place the chairs for them. Also when he saw that the elementary kid-teachers were getting upset or were in a bad mood, he began to play with his nunchucks and it made the atmosphere lighter. Then he asked them "did the mood got better?". He looked so warmㅠㅠ he was also asking them if they were cold and was the first to go up to greet themㅇㅇ
