Shimekiri Mijikashi Yumemiyo Sensei

Tomomi Kanbayashi, a junior high school student who dreams of becoming a novelist, has a secret that she can't tell anyone. It's about the creative methods of best-selling novelist Masaharu Shukunami. Shukunami's creative process, which produces hit after hit, requires... "dreams"!? Kanbayashi, who studies under Shukunami, puts Shukunami to bed so that he will have good dreams today too!

"Teacher, please go to sleep!"
