Mashiroiro Symphony is quite a enjoyable story with some tedious and boring bits, but most animes are like that, i enjoy that each character are different from one another implying different feelings/emotions while still being in a harem.
The major thing i didn't like about it was that main guy didn't show as much of a strong "hero" i just saw a lovable over-friendly side character, and personally thought the girls had more interesting stories then the main character.
