It's all started with Arrie, a very shy boy who decided to work at a second-hand book store.

North and East were the most popular boys in their middle school, chased relentlessly by girls. As boys, they pretended to be a couple to get the girls off their backs. When they meet again in college, years have passed, much has changed, and real love begins to blossom.
