So it's 2016 already and HAPPY NEW YEAR to all you beautiful people out there, I hope everything goes right for y'all! (: Here's a little stand-alone sequel to When Maths Meets Lit, and Baek retaliates with a scientific explanation of how people fall in love, at the same time destroying the beautiful notion of soulmates. (Okay I'm sorry if I ruined fantasies with this one-shot haha don't kill me I just wanted to give Baek his chance to show off his science-y knowledge xD)
