A ton of very cute mini-stories here. Wonderful. My favorites might be the mom bits.
Also, thanks, hidekins, for linking to the Umi SID! I'd read the manga version of the Maki-forced-to-quit chapters, but hadn't seen the others.
(Boy, the School Idol Diaries sure are shippy, aren't they? Besides Umi's obvious adoration of Honoka — and Umi's mom apparently being ready for Honoka to marry into the family — and Kotori, they managed to fit in some EliUmi, MakiUmi, and NicoUmi.)
