Please listen to these 2 songs, both titled “Fuwa Fuwa Time” from anime K-On series.
Personally, I prefer Yui version to Mio version :mrgreen:. Her voice (seiyuu Aki Toyosaki) kinda cute and somehow fit to the moe atmosphere of the anime (though Mio also has another moe factor :lol:)
So, what about you? Which one you prefer? 😉
