To celebrate Valentine's Day, an unnamed student at Troy High School in Troy, Ohio, treated the entire student body to a heartfelt and handmade surprise.

As the 1,504 students shuffled into school on the morning of February 14, they were greeted by a rainbow of beautiful origami hearts taped to their lockers. Each brightly colored work of art was adorned with a simple and sentimental sentence—”you are loved”—and purposely showed no indication of the gift giver's identity.

Besides the mysterious artist his or herself, members of the school's faculty appear to be the only ones in on the secret, as detailed in a festive Facebook post. “This actually turned out to be 1 student who wishes to remain anonymous,” the school shared on social media. “These are individually hand written origami hearts that this person started working on back in September. This person has been secretly storing them in their closet at home to surprise everyone today.”

In a heartwarming turn of events, it seems that pupils at Troy High School weren't the only students treated to an anonymous Valentine's day treat this year. In numerous high schools and elementary schools, unidentified students decorated lockers with lollipops, personalized magnets, and uplifting notes.

Looks like love is in the air—and in bustling high school hallways!

In a touching Facebook post, Troy High School shared photos of the mysterious treats.

And, fortunately, it seems students at other schools had the same sweet idea!
