   Summary

   I never expected my final year of school to be defined by late-night lab reports, volatile hypotheses... and Tetsurō Kuroo.
   Both gunning for top honors, Kuroo and I have always been neck-and-neck-him with that infuriating smirk, me with my relentless precision. So when I'm assigned to co-lead a high-stakes science project, it's a disaster waiting to happen. Heated arguments. Teasing glances. Lab explosions-some chemical, some emotional.
   Something fragile. Something real.
