I like Marina but I love Lily as she's my ult dreamie lol so I was pretty biased on who I chose but I'd suggest you get Marina's framed photo first if you haven't yet that way if you did invite Lily and end up liking her more than Marina then at least you'd have her framed photo already for memories sake
plus you won't have to worry about building your friendship up again for Marina if you do end up inviting her back since the end game of the friendship is getting their framed photo anyways (well at least for me lol) and you could just take your time rebuilding it naturally...
