I think so. I mean, as a guest user you have no backup of things. While with line you do. I'm sorry but as far as I know, logging in with a LINE account will certainly delete your guest user.(happened to me with other line games). I'm sorry but I hope you can keep playing as a guest or deciding to login in. Best of luck!
