Kousuke is a high school student. He just recently found out that his childhood friend Shizuka (whom he has a crush on) is now going to his high school. However, they havent seen each other since they were five and much has changed. They dont like each other at first but they accept each others differences and continue their friendship. They go on with their lives until small events start to escalate and they start to show affection for each other. In the meantime, Kousukes good heart, lechery and luck lead him into the beds of various other young women, in his attempts to solve their problems.
