Adva chose to go with Mushi

"Thanks for taking me here Roseo, but I think I'm safe enough here in town, and I'll really love to check out Mushi's library" Adva responded, she was excited to get to explore a new library from another world filled with information that she had never learn about before, that was a dream come true for a nerdy bookworm like her.

"Ok then, enjoy those books, I'm sure you'll get what you need to write your own, I'll see ya around" Roseo responded not taking it personal that she would rather go with Mushi to explore his library, he then turned around to the parasect and asked him "Can I trust you'll look after her?"

"Of course, I may be a bit old, but I'm no pushover either, you know that Roseo" Mushi reasured the roserade femboy.

Roserade nodded in response and waved towards the 2 as he continued on his way, Mushi then turned towards Adva and told her.

"Alright miss Adva, follow me, my librarry is nearby" he said as he began walking down the street, he was kind of slow so Adva had to limit her own speed to not passed through her guide, by the time that they reached the library it was already getting dark, the library was a cute looking building, similar to the houses that the resident lived on through that town but unless most places it had a second story, the door had a painting decorating it showing an open book which had the saying "knowledge is power" written over it, Mushi open the door and showed Adva the inside, and she looked around in wonder, as every single inch of the walls were filled with bookshelfs filled to the brim with books, it was beautiful she didn't knew where to begin to read.

"hehehe I can see you like what you see young girl, I'm happy, there aren't a lot of pokemon that get pationate about books around here" Mushi said happy to see her as ecxited for his librery as a kid on a candy store.

"this is wonderful? the 2 floors are just like this?" she asked hoping that the second floor was just as full.

"I'm afraid not miss Adva, the second floor is for me to live on, I've a room, a bathroom and a kitchen there, if you don't have a place to stay yet, I could make a space for you" he offered to his visitor.

"Really? wow mister Mushi you're so kind, yes I'll love to stay here" she say thinking now that this world may not be so bad after all.

"Yeah, but before I need to ask a favor of you, quid pro quo basically"

Adva was familiar with the term it means to give something so you may get something back "ok mister Mushi, How can I help you?
