The reason? I think it's
very 6+1 was also taken by him. He thinks that the number itself is very easy to be remembered as a concept, (6+1=7) and it's true that we are just six days of training and one day of exhibition, which happens to be broadcast on the evening of the seventh. Many meanings are put in it, and it's easier to operate by transforming it into icons. Maybe "52" also has this factor ~
For example, 52 refers to 52 weeks of a year, and every week is lucky. Of course, it is called lucky 52.
The "V" gesture means victory
And it means I love you, hehe.
