Falling in love is a chemical reaction. Just ask Kaya Rubio, twenty-five year-old Molecular Genetics graduate student and research assistant. Fed up with her spinster aunts' relentless reminders and unsolicited advice regarding her Single Since Birth status, she designs a scientific, evidence-based methodology to find her a suitable partner in time for her cousin's wedding. As any good scientist knows, any valid experimental design requires a negative control. Enter the most unsuitable candidate for a potential boyfriend: the messy, easygoing, café owner Nero Sison. Her null hypothesis? Going out with Nero would establish her baseline data without catalyzing the chemical reaction she seeks. But when Kaya's recorded results refuse to make sense, she is forced to come to the conclusion that there are some things in life that are simply, by nature, irrational and illogical. And that sometimes, chemistry doesn't always happen inside a lab.

Falling in love is nothing short of a natural disaster. Just ask Phylle, climate scientist on board a research cruise off to unexplored waters. She’s finally on the brink of a personal epiphany—while battling her scientific demons—and she’s determined not to be distracted from her cause. Dakila knows that what he has is less of a full-time job and more of a calling. As an award-winning journalist, he has stood in the path of typhoons and faced danger head-on in war zones, but nothing could have ever prepared him for the storm that is Phylle. Phylle and Dakila both understand that saving the Earth means no time for relationships. But every dive and surface interval leads them closer and closer to a different kind of discovery. One neither of them could have ever trained for. Maybe it’s about time they ask themselves: What's a sustainable future without someone to share it with?
