So... not that long ago I read à kaisoo fic and I really wanna read it again. 

Kai is a painter and Kyungsoo is his boyfriend, with I think tattoos too.

It starts with soo going to an exhibition and watching kais paintings, and the secretarys (?) Not believing him for being someone near to kai. 

Also kai is rich but Kyungsoo still wants to work himself.

is involved and I'm not sure about toys.  

It would be really nice if you could help me^^
