Doraemon: Nobita Nobi's Chat Group

Ding! Welcome to the Nobi chat group.

A voice rang out in Nobita's mind. Confused, he looked around, about to ask Doraemon what was going on, when his eyes instinctively fell on the alarm clock on his desk. Realizing he was about to be late, he paid no more attention to the voice that had suddenly appeared beside his ear. He hurriedly grabbed his schoolbag and ran out of the room. (I don't know how to write a blurb, so I'll just copy the beginning of the story. I haven't decided whether there'll be one heroine or two; I'll see how things go later. Shizuka has no chance, though.)
