How to check/know how much Suspicion Yuna have?
At the moment, I do not believe there is a way to see the value. Forgetting to clean up after yourself or letting Kan see her exposed adds to her suspicion. Try to avoid those.
As long as you cleaned up/put her clothes back on before leaving, she'll be less suspicious
Hi,
Dev plans to add some kind of indicator informing us about her being suspicious or not, so it'll be easier to know.
Cheers
