Spoiler for For true ending:

Actually, we won't be able to know if they will go with the true ending until around 1 or 2 episodes before the final episode of Refrain (can be compared to After Story of Clannad in a few ways)

I'm pretty sure that is isn't a spoiler

Spoiler for not really a spoiler but in a spoiler due to request:

because it's officially known that Rin is the main heroine of the anime/game.
