Stargazing: Your Voice - Rhodanthe*
Cute girls doing even cuter things. Kiniro Mosaic is undoubtedly moé to the bone, but I also find it charming and enjoyably funny as well.
For slice-of-life series like this, it's integral that every character in the main group is likeable so the entire show doesn't grind to a halt for certain characters. Luckily, it's nigh impossible to dislike anyone in Kiniro Mosaic, and their jazzy ending song as a group is irresistible.
