Oh my great friend, I'm still waiting for your post, apparently you posted it 5 days ago.. 😅
Forgive me for only now I visited your post.
I just found out about this anime, because in my country this anime is not shown on television. But I hear you sing this song I feel the memories of childhood are so cheerful.
I like the two versions you sing. The first version is very natural and the second version is very cheerful.
