After you defeated those two monsters that were protecting the entrance to the temple, you found Yue in a flying rhombus.

(wtf is the lore don't judge me)

She told you that she had been betrayed just like you, so you decided to take her out and give her the name Yue. That's the past. Let's go back to the present. Now you two are at the end of the labyrinth in a mansion that Yue found and right now Yue is on top of you.

The question that I always ask some characters, what will you do? "Will you say something to her or hug her and enjoy the moment"
