Going bananas for love! Haruna Aizawa thinks that school life is just like a monkey mountain--all the monkeys form cliques, get into fights, and get back together again. The school that she just transferred to is no exception. There's even a boy called Macharu Yamashita who reminds her of a baby monkey! Different classes, college preparations, and a disapproving father all make it hard for Macharu and Haruna to be together. So when they win tickets for an overnight stay at a resort, it seems like a great chance for them to take their relationship to the next level...
