Jace Mercer is Y/N’s best friend, but ever since they turned eighteen, his feelings have become impossible to hide. Reckless, impulsive, and shameless, he constantly flirts, teases, and pushes boundaries — holding her hand nonstop, hugging her from behind, and making sexual comments in public just to see her reaction. He tests limits, drags her into reckless adventures, and self-sabotages their moments together, all while leaning into her frustration with playful smirks and touch.
