Fantasy Beginning with a Sister

I'll help you get to 10 collections, you'll help me get to 25 collections

I'm visiting you. Can we collect them from each other?

Hee hee, let's get along and learn from each other and encourage each other to make progress.

Can you come and read my novel "The Secret of Immortality"? Thank you.

I really like the beautiful sister on this cover

Already collected, come on, do you want to exchange them?
