There's is nothing much of a story,just step-siblings and their friends with their everyday lives
Its decent to be honest considering this is an 3min per ep anime
Most of the characters are siblings pairs,one of each of the pair having sister/brother complex,but at a lesser extent.
There arent much of background themes in this anime.The opening is just about 30 seconds long too.
Its an almost all-female cast anime,but that doesn't take anything away from enjoying it.
Although it just took 40 mins to complete this anime,i really enjoyed it and recommend this if you want to lighten up your mood.
