Summary: (Its the format that is used by creators making themselves as two different characters to give skit themed reel, and in this specific reel he gives a tip to be productive and then says that just because I liked the tip I am going to follow you.)
self praise CTA to increase your authority
Why it works:
It works because viewers see themselves as part of the video or see representation of their views and thoughts in video and ultimately they engage or respond back.
A CTA move wrapped in a two character skit, both characters played by the creator. One has a problem, the other gives a genuinely useful piece of advice, and the first closes by announcing out loud that they are going to follow because of it. The self praise the page describes is never spoken by the creator as themselves. It arrives as a line of dialogue from the character standing in for the viewer.
Asking for a follow makes the creator the one who wants something. Putting the ask inside a character's mouth reverses the direction, so the viewer is now watching someone else react the way they are already half reacting. "Yo, that's actually genius. I'm following you just for that" is a script for a feeling the viewer is having, and people tend to finish a sentence somebody else started for them.
The skit frame also launders the compliment. "This tip is genius" said to camera by its author is a claim, and claims get argued with. The same words said by a second character inside a scene are a reaction, and nobody argues with a reaction. That is the entire reason the ask is wrapped rather than spoken, and it is close to what the page already says about viewers seeing their own response represented in the video.
All of which only holds if the middle is real. The compliment at the end is a verdict on the advice, so thin advice leaves the verdict visibly unearned and the whole thing reads as a creator praising themselves through a costume change. The value has to be something a viewer would repeat to a friend without attribution. In the primary example that is a specific mechanism, deliberately sitting in boredom until the boredom pushes you into the task, rather than a platitude about focus.
One thing the examples make clear: the closing line is not an instruction to the audience. It is the other character narrating their own decision, in the first person, past the point of choice. Nobody is told to follow. Somebody is shown following.
The ask lands on the final beat, but the skit is the whole video, so the move runs across it rather than sitting at a timestamp. The wrap is what makes that last line legal.
