I thought I’d never like the rain. And I didn’t care if things stayed that way forever. But then I met Mr. Osada, and something in me changed. I fell in love with it. Whenever it rains, those memories come rushing back to me. So, please, let the sun come out soon and make them all go away. In the library during the rainy season, Wataru, a member of the library committee, meets Mr. Osada, a science teacher who has only just been posted to the school this year. Through the time he spends with Mr. Osada, Wataru learns a great deal and comes to face his own feelings.
