Urahara Dreaming

College student Tatara often has dreams. Lately, the one he sees most frequently is about his friend named "Gaku." Gaku is an imaginary friend who only appears in dreams, but being with this kind, cheerful guy is fun and healing. Honestly, Tatara's gotten to the point where he's happy just to meet him in dreams and even looks forward to going to sleep.Then one day, just when he thought Gaku had shown up in his dream as usual, Tatara suddenly gets pushed down?!?
