When it comes to NCT‘s Mark, there’s no debate about Yuta being among the people who love him most.

During Mark’s latest Instagram live, Yuta amused fans by showing how much of a fanboy he is for the younger member.

As soon as Yuta tuned into the live, he commented multiple times to get Mark’s attention: “Hi Mark. Mark. Mark. Mark?

Going full fanboy, Yuta had a request for Mark. He commented, “Can you call my name?” While some members’ comments get lost in the sauce during Instagram lives, it didn’t escape Mark’s notice.

As soon as Mark saw the comment, he fulfilled his number one fan’s wish—not once but twice. When Mark spotted Yuta’s comment, “Thank you,” he couldn’t help but burst into laughter.

No matter what Mark does, Yuta will always be in the front row cheering him on.
