Thank you for playing! I'm happy to hear that you enjoyed the demo! ^^
Sadly, I can't say anything about the 7th romance option nor about the card drawing sequence since both of those things are spoiler territory. The full version of the game will hold an answer those questions.
I'm also happy to hear that Isshin and Marco got to your liking! ^^ I put a lot of thought into the story and the characters themselves, so I'm always flattered to hear such kind words regarding either.
