Your right. That scene confused me to. It was so random and came out of nowhere. Were they rehearsing a scene…
No problem. When Peek and Kla were first introduced in War of Managers they were already a shipped couple on their university campus where they were both moons. They had a growing FC but they weren't a professional couple until Toon picked up on their popularity and showed it to Pla. They agreed to manage them together. It was a new start for the two managers after making up with each other.
From the flashback in that episode we see that it all started when Kla would tease Peek and people began to ship them. In university it was fun and they maybe made a little extra cash but Peek was hesitant to go professional. It was really Kla who encouraged him to go professional and take up Toon and Pla's offer so he could help out his family. It's only now we are learning the real reason Peek was so hesitant. Not only because of his father's attitude but probably because he had real feelings for Kla and was afraid of that coming out.
The 3rd story started off good but now it's just really boring, there is a lot going on but nothing really happens.…
When they were doing the mirror exercise with the acting couch Peek had a flashback to their university moon days when one of their classmates was writing fanfiction about them. That whole scene was real except for Peek imagining the fanfic playing out on the stage. When Peek remembers how Kla has always looked out for him he knows he is being sincere and finally lets his guard down and opens up to Kla.
