I am having some trouble. I had the sake scene, and Tanabe saw her in the shower and, later, gave his phone number.
After this I cannot trigger any more scenes.
I have tried with having her have high (90+) and low (>10) frustration, but eventually the blue sky ending scene comes.
Her purity is generally rather low, around 5- 10.
Does anyone have any tips on how to trigger more scenes with Tanabe, and, also, what how to avoid the triggers that lead to her talking about she does not want to live like this anymore (which leads to the blue sky ending scene)?
