When calm meets chaos, sarcasm meets smiles... and a 2nd yr. Pharm.D ends up tutoring a 3rd yr. med student who can't tell a beta-blocker from bubble tea. Santa, a top Pharmacy student with a no-nonsense attitude and a killer side-eye, gets forced to tutor Perth-Chula University's most handsome walking disaster. Perth is charming, late to everything, and allergic to seriousness. What starts as a forced academic arrangement soon spirals into late-night study sessions, unexpected heartbeats, and a lesson neither of them saw coming. In a world of caffeine-fueled exams, stolen glances, and sarcastic banter, love might just be the most confusing subject of all.
