まるを踏んづけた後、一人盛り上がって遊ぶはな。
After stamping Maru, Hana plays happily alone.
を、背後からじーっと見ているまる。
And Maru stares at her.
まる:「ひとりで遊ぶとはけしからん!」
Maru:[Though a playfellow is here, why do you play by yourself?]
まるははなと遊ぶのが一番楽しいみたいだけど、
はなはまだまだひとり遊びも楽しいお年頃。
It is the most pleasant for Maru to play with Hana.
But Hana is still young, so she also likes to play by oneself very much.
