Lee Sunkyun and Jang Hangjoon, the 'hyung line' of four private travelers, Lee Sunkyun recommended Jang Hangjoon as his travel mate, saying, "He is the most interesting person I know." Jang Hangjoon joined this trip also because of Lee Sunkyun. That's why the two picked each...

other as their best travel mates. LSK called JHJ a "happy virus," calling him a "new discovery." JHJ remembered LSK as the "most interesting travel mate." JHJ played pranks on LSK without even trying, and his personal reason for joining this trip was “to tease Lee Sunkyun.”

JHJ said, "Lee Sunkyun is a character who feels unfair about everything, so it feels good when I joke with him,” "Personally, Sunkyun was the cutest." "Other people don't know, but if you look at it, it's cute like a child," he continued.

LSK said, "I was really curious about the chemistry of this travellers union. I was looking forward to seeing how relationships that we are not familiar with will communicate and develop." LSK, the 'outward leader', said, "I don't really like to lead anyone or be led by someone,

so the expression of a leader was burdensome. But no one followed me well, so it was less burdensome." Lee Sunkyun said, "I think the changing relationship will be interesting. Please watch how the first episode turns into familiarity, pleasantness, intimacy, and tiredness."
