One day, I went to school with Semin. It was raining, and Semin singing the song "Singing in the rain"!
We walked to school together, I like this song. From now on, I hear this song, I will miss my friend--Semin. So I wanna introduce to you all. This song was a theme for a miscal movie " Singin' in the rain" in 1952,also check wikipedia to see more information.
