Title: Toothbrush Effect
Author: KnoW_logic
Genre: Comedy/Fluff
Pairing: Sehun x OC
Summary: Guys her age didn't know how to treat her, didn't know how to touch her, didn't know how to keep her, and definitely didn't know how to love her good, until she met Oh Sehun.

Lost among Seoul, the big city of South Korea, Song Soo-ah’s college degree in science, specifically chemistry, is as useless as her luck in finding guys. She's 25 years old and living in the drains, working at a café. Unlike her successful roommate, she's never had a boyfriend and everyone who knows is persistent about it. She just wanted someone who would treat her right and love her right, but she never thought about finding someone younger than her. The guy that made her look like a fool at the local convenience store in the toothbrush aisle just happened to be the same guy that made her fall in love.
