Im playing through steam on PC. I've gone down all the right options for a Siora romance and it gets to the point where she asks for some alone time and i say come find me outside my room the next time we are at the house and nothing ever triggers. Ive seen reddit posts and steam discussions posts with other people having the same issue, it seems to happen if you're in the house when this dialogue option comes up. The romance story was really what got me through the bulk of the main story until things started getting way interesting. I've finished the game but without seeing how that romance plays into it im a little disappointed, i really hope this can be something thats patched and i can go back and complete the last quest and see for myself, youtube videos dont have quite the same impact for me.
Great game i loved it, everyone involved should be proud!
