Eun Si-An is the main character of the story. She's a caring and selfless person, but can't interact at all with guys.

Eun Si-An, otherwise known as Shanshan by her good friend Hyunee, is popular with all the girls at school. Which would be great if she swung that way, but she doesn’t. It just happens that she’s terrified of men, and her mother is obsessed with protecting her from all men. And suddenly, Yu-Ri, the prettiest girl at school, has admitted to Si-An that she has feelings for her. Now Yu-Ri won’t stop following Si-An around, which would also be fine by Si-An, except it seems like Yu-Ri wants Si-An all to herself... and who knows how far she’ll go to make sure that happens.
