I got it after quite a number of attempts. The dialogue for scene is related to mc's broken leg.Is it worth doing the whole route for that last image?
What part of the dialogue does it give?
To get it, we have to be nice with Elliette (in order to get the Elliete bathroom scene).
Then, I picked the option to endure the pain (not sure if this has an effect on getting the scene) and decided to go with sheina.
