This work began on the day when Yamashita and Kobayashi had made an extra big candy like a bowling ball by themselves (dia. 180mm).
Since that day, they kept licking the candy day after day for about six months. While they were licking, a lot of episodes happened (the change of the seasons, even change of the house...).
We continued to lick with the aim of only creating an ordinary candy, which seems just a candy on the market.
