Manga Like The Secret of Friendship

Eiko and her best friend Moe couldn't be more different: Eiko is a shy, average-looking girl while Moe is beautiful and envied by everyone at their high school. Though their personalities are total opposites, the bond between them is incredibly strong. Moe might have an endless supply of suitors, but when it comes to actually dating them, she has a condition: her boyfriend must value Eiko more than he does Moe. No one has yet been able to meet her condition—not until a boy named Tsuchida appears, at least. What will Eiko do when her relationship with her best friend begins to change?
