Barairo Guardian

Kasuga Koharu is a small "runty" type of girl, who is forced to join "The Guardian Rose", by the clubs directer for her prestigious school. "The Garden Rose" is a group that tends to the rose gardens on the grounds. Curiously, Koharu goes to see the garden, but is surprised to see in the garden, a popular and smart young man dressed like a prince. His name is Jordan Kiriya, and sexual intentions are sure to ensure!
