From this Variety review of Blush at the Tribeca Film Festival back in June:

At Disney Animation, where he worked for 25 years, rising to head of story on “Big Hero 6,” Mateo started out as a clean-up artist and 2D animator.

And:

“Blush” is inspired by Mateo’s wife, Mary Ann, who lost an eight-year battle against breast cancer in 2017.

And:

After I lost Mary Ann, I suddenly couldn’t breathe, it was a scary moment. I had to call a friend who is a doctor and ask him: ‘What is going on with me?’ He said: ‘Joe, you are having a panic attack. I realized that Mary Ann was my air. I was struggling to breathe because I lost my air.

With that in mind, watch the trailer embedded below. Blush (an animated short) goes live on Apple TV+ on Friday.
