The Ranma/Akane Fanlisting
This site is a fanlisting (FL), which is basically a list of fans declaring their love for a subject. (More about that here.)
"Best Left Unsaid" is about the relationship (either romantic or platonic, but you obviously see my bias) between Saotome Ranma and Tendo Akane from Rumiko Takahashi's hit manga series, Ranma 1/2. At the beginning of the series, these two were engaged against their will by their fathers, who wished to unite their martial arts schools through their children's marriage. The series focused on the development between the two stubborn teenagers as they resist and deny their growing feelings for each other, despite the strange circumstances that brought them together.
If you're curious about why they are one of my childhood OTPs, here's a brief explanation.
