From SuBLime:
Oku-san is a normal office worker who has one joy in life, to fantasize about his local deliveryman, Sudo-kun. To feed his fantasies and his desire to see Sudo-kun, Oku-san habitually shops online filling his room with useless and sometimes very erotic things. It’s all pretty harmless until one day his neighbor Yokoshima finds out about his secret hobby. Caught between two hot guys -- at least in his mind -- will Oku-san be able to fantasize his way out of this one?
