Apparently there is a secret third ending with Siri after you completed BOTH of his and Eleni's good end but I don't know how 🤷♀️
And I agree with you Luca's route makes me cry like a baby
To those who haven't gotten this ending, you would have to go back to Eleni's good route after Siri's success ending to meet him again, then there would be two choices that would ask you if you've seen him before or not. To get the third ending for both Eleni and Siri, you'd have to say you've seen him before.
