Wang Ren had discovered several times that Wu Mu, who was watching from the sidelines, often cast his gaze on the very thing they were about to focus on in the next shot before their camera did.
For instance, in the scene currently being filmed, it was about a conversation between Wang An and the foster son he had found.
For most people watching from the side, their attention was mainly on what the two were saying.
But here, Wang Ren intended to give a centerpiece shot to the red sweater worn by Wang An, a sweater that had started to unravel.
Then he noticed that Wu Mu, standing by, had already fixated his gaze on that sweater before their close-up shots had even shifted in that direction.
If Wu Mu had peeked at the storyboard ahead of time or listened to their pre-filming discussion, then it wouldn't be surprising for him to notice.
But Wang Ren clearly remembered that Wu Mu had just been resting in the break area and hadn't paid any attention to this side at all.
