Nope already got caught by her, and had whole agreement thing with Ymir, I'm talking about this one: "I should try playing with Christa at night again... and when I have the chance, I'll put a blindfold on her eyes and let Ymir have a turn with her... then I can talk about with Ymir, heh."
How do I start making progress on Christa's quest which requires MC to further the nightly ventures with her so when MC goes to Emir, I get to decide what She'll do for MC in return?
