Dear diary, 

Today was the first day of the last year of school. I reunited with all my girl group members except for Mina, because she was still in Japan visiting her family. I missed the other girls too, but my heart was especially aching to see Mina. I don't understand why. Maybe because I thought about her the most during the summer? I don't understand that either. I am closer with Jeongyeon than I am with Mina, so why is Mina the one taking over my mind? I hope I can find out what is wrong with me soon. 

Yours, 

Chaeng
