Here's one more in the same day. This anime series is not very well known and needs more love. It's a fun bright series and very heartwarming (as its title can tell you), and it has a fun little OP, in C Major no less! Seriously, whatever bland harem/slice of life/shounen/fantasy series you're watching is probably not worth enough to justify not dropping it and watching this (and then downloading my transcription and leaving a thank you). No, I wasn't watching old anime when I had free time to transcribe songs...
