Nee-sama, once again, happy birthday

Kiito, happy birthday to you too

Ha-a, after all, it's calmer to be alone with you, nee-sama......

Well, you say that

When we were alone, we always celebrated like this, but... It's not bad to celebrate with everyone, right?

A-As long as I can celebrate with you, nee-sama......

But when you say that, it makes it harder for someone who wants to celebrate with us to come out

Yuki-nee...!
