Yeonjun (TXT) x Wooyoung, Yeosang and San (ATEEZ) is the cutest friendship ever.

It goes back to when they were still trainees- they got close because they were the only 99 liners at the time. Meanwhile, San and Yeonjun were classmates in high school and always ate together.

Both the groups, especially Wooyoung and Yeonjun often give shout-outs to each other on Vlives and shows and are really supportive of each other.
