Switch From switch to pc

[Dracuana]

Hi!!,

Is there a way to install stardew valley in pc for “free” if I have the switch version????
I wanna play with my friend that is a pc player but it doesn’t allow cross play (I also have the game in mobile form)
Do I have to buy the pc version

thanks all of you in advance

btw sorry if I made any grammar or spelling mistakes English is not my first language

bye
