Hi! Thanks so much for playing! Here's a quick guide for Santana/Lucy points. Also, looking into this I found a bug that I think might be preventing their meals from being accessable, so I will fix that in an update this wek!:

None
Ch 2:
During feeroam, catch Santana in the square and ask why he stole from you.
When Lucy insists Santana didn't steal the book, say "I guess that is strange."
Ch 3:
Walk around at the ball.
Get some food at the ball.
Ask Lucy to dance.
Ask Santana to dance.
Ch 4:
Tell Lucy you'll help fix the carriage.
Order for yourself when eating with Lucy, then gossip about Aldrich and Leslie. Play along with him, too.
Tell Lucy you'll spar with them.
Say to Santana "so you can't read, huh?"
Invite Santana/Lucy along to any side quests.
