This is a picture of Akita Neru singing the song Why don't you call me yet? originally by Rin Kagamine.
I listened to this song, and I wanted to make a fan art of it, then I felt like drawing Neru, so this came to life. I'm pretty sure I didn't get the clothes right, but this was what I drew and I didn't feel like fixing it. So, the story is:

Neru and Len are boyfriend and girlfriend. Neru likes Len very much, but Len likes Rin. One day, he doesn't call her. Neru keeps waiting, but he never does. He is late for a date, and Neru suspects he's seeing someone else. When Len doesn't call the next day, Neru decides she won't forgive him. Then Len calls Neru to apologize for being late, but she doesn't answer her phone.

Um, please comment if it doesn't make sense.
I might make a drawing of Len's side of this later. Oh yeah, in the picture, she's dropping her phone when Len's calling.

Hope you like it! ^_^
