Dallin Knecht proposed to preschool teacher Sara Trigero with the help of her beloved students on Nov. 3 in Reno, Nevada.

“Sara cares a lot about the kids,” Knecht, 26, told ABC News. “She's there full time, spending eight-plus hours a day with them, and loves them a lot.”

Trigero, 27, is a teacher at the Child and Family Research Center at University of Nevada-Reno. After she left a fake performance review with her boss, she walked outside to discover the pint-size surprise.

The preschoolers scramble to get set up for the big reveal.

“My boss pretended like I had a meeting with her to talk about my performance,” she explained. “While I went out and had my meeting, they set up everything outside. But it wasn’t a real meeting at all. It was totally pretend. Right when I walked out the doors, I saw them.”

Knecht had gathered her 2- and 3-year-old students in the university’s quad, where Trigero said “there’s always things going on,” so she was about to walk right past them until she read her special sign: “Sara, say yes.”
