Chen Ming activated the [Director's Eye] in an accident (specifically: he fell down the stairs and landed on his head when moving, and when he woke up, he found a viewfinder in front of his eyes).
When looking at any person/scene, movie-level framing, composition lines, light analysis, and - most importantly - the "emotional realism" percentage value above the character's head will automatically appear in the field of view.
This value shows the "true degree" of a person's current performance. 100% = Totally truthful, 0% = Totally acting/lying.
When looking through a viewfinder (any lens), he has an enhanced ability to see a person's "key memory fragments" flash forward in the form of movie frames.
Every time you complete a work (short film/long film/short video), you will gain ability points based on the "realism score" of the work and unlock new features. Lin Qi is the only person he has ever seen whose "authenticity" has remained above 95% for a long time.
All the other women - Jiang Wei 70%, Shen Zhi 65%, Gu Nian 30% - have a lot of "acting" content. Only Lin Qi hardly acted. This data-level comparison provides a system-level explanation for "the only woman I haven't touched".
