Liam Carter is a perfectionist with a sharp tongue and a planner full of color-coded dreams. Max Harrison is the golden boy with a charming grin and a knack for driving Liam up the wall. For years, they’ve battled in everything, from grades to student council speeches, earning the title of Frenemy Kings at their school.

But when their school launches an anonymous Pen-Pal Programme, neither expects much.

Under the code names Quill and Atlas, snark turns into banter. Walls start to crack. Vulnerabilities slip through ink and paper. And slowly, terrifyingly, they begin falling for the person behind the letters, not knowing they’ve been writing to each other all along.

Told through a mix of letters, quiet moments, and hallway glances, Signed, Your Rival is a short story of LGBTQ+ rivals-to-lovers high school romance about vulnerability, identity, and the kind of love that finds you when you least expect it.
