Both the Slice of Life CGDCT manga well in the Iyashikei genre are about a small group of characters getting up to various antics irrelevant to any (non-existent) plot, though where in Shinmai Shimai the antics are making food, in Mitsuboshi Colors it's playing around town.
Nigh all chapters are heartwarming with little to no serious stories, and in all of them one can experience the joy of seeing cute girls be happy and cute and have fun. The type of cuteness and the degree of seriousness reflects the age of the main characters, but the feeling the reader experiences is almost identical.
