You're right, it's the first time when you meet Juliette so don't bother yourself with her relationship points. Just raise your lust to the max to be sure it'll trigger the scene. Although, there's no CG for this particular scene, only "pixel-art", so you'll get nothing here fap material wise...but isn't that the first time we met her how can we raise relationship point with her when we just met her the first time ?? or i have to raise it in the basement first then rescued her later?
