I never mind answering questions. I love it! :D
1. Is there a chance to fail the romances?
No, none. Once you're in their route there's no way they'll fall out of love with the MC.
I find it a bit silly (and annoying if it's a RO I like) when ROs can reject the MC in IFs. I understand the logic behind it, but it makes me feel that I can't play without a guide in hand. Obviously, the ROs shouldn't have to instantly like the MC and approve everything they say or do, but to have the chance of them breaking up with the MC... I'm glad for those authors who like it and add it to their stories, but it's a feature that will never be on mine.
2. On a scale 1-10 how angst filled are the RO routes?
It depends on what you consider to be angst. I think all of them have a bit of angst in them, but maybe I believe one of them is a 7, and for you is a 4, lol!
I'd say it's like this:
Ada/Omar: 6, maybe more if the MC knows they're in love.
Albert/Lavina: 2
Leire/Luca: 8
Rayco/Gara: 9
But! Keep in mind that the angst will stop for all of them except Rayco/Gara the moment they get together, so most of the time it will be more fluff than angst :D
3. On a scale 1-10 how fluff filled are the routes after establishing a relationship?
Like the second question, it depends on your definition of fluff, but for me is:
Ada/Omar: 5
Albert/Lavina: 9
Leire/Luca: 7
Rayco/Gara: 8
Thanks for the ask!! ❤️❤️
