"I used to think that some subtle feelings I portrayed were uniquely my own, and wondered if I was too sensitive. But when I draw them, others tell me that the work strikes a chord with them, then my narcissism collapses and I realize that I am not that different from other people," says Yu.

"It gives me a strange sense of warmth, and makes me feel like I don't need to be too scared or too proud facing the world. That's really good."

Creators just need to experience their true emotions and express them in their works, so that the sincerity will touch others," says Yu.
