Yixin was Meng Fan's editor-in-chief. Even the unsigned "Guide to Campus RoMANce" was managed by his team. No need to mention how good Meng Fan's drawing skills and painting style were; it went without saying. Of course, it's weird how visible the difference was in his level in the previous serialized comics and in what they were looking at now. However, the better the paintings, the better. No matter how strange it was, you can't question it face to face.
What's the use of questioning anyways, other than not allowing people to improve? It's only that this progress was really great, that's all.
The deputy editor-in-chief and the others had also seen Meng Fan's comics and knew about Meng Fan's drawing skills, so after unfolding the sketches, even though they could see the beauty of the world, they weren't as amazed as Goro Takahashi and others.
But after looking at the paintings, they moved on to storyline and character design, and their eyes lit up again.
