Hello there,
Negative, Emma is for arresting Mario, while Sofia is when siding with Mario
Sliding with Mario has to be the least favorite choice in Starmaker Story as it's more satisfying to dunk him for the snake he is. I believe Muramasa shares similar opinion based on last discussion we had on a similar post.
It's for the sake of keeping exclusive content for player's choices as the tag implies. I do hope devs will consider an alternative way perhaps if majority of players share similar opinion.
In my opinion, even if I wanted to take Sofia to the farm and have her in the guest room, it's not worth it considering we lose Emma's invitation to the farm and the cryptid quest. There should be some option like: betraying Sofia, she ends up in the guest room, and then Emma discovers the information about the cryptids and asks if we can help put Mario in jail.
