After hearing tiny portion of the opening theme so many times on this-and-that internet radios, I had to buy this. I just love the "daisuki dayo, kono omoi wa todoiteru kana, egao wa kotaete kureru kana" verse.
The ending song is a new arrangement of the original song sung by Nakatsukasa Masami. Original one is much nicer. I would have given a 'B' grade for just the OP.
Extra '-' is for lifeless-sounding recording.
