ちょっとだけおっきくなったよ！な夏の永遠亭

タグ「こどもこ」って……！！！ツボにはいりましたｗ嬉しいです！ありがとうございます！！

It's a "They've only gotten a little bigger!" summer at Eientei.

And that "Mokid" tag...! It's right on the money. lol I'm so happy! Thank you so much!!
"Mokid" = "Mokou" + "kid". The original tag is "kodomo" + "Mokou" = "Kodomoko".
