Man, thanks for your very detailed answer,I really appreciate it, but unfortunately, you did not answer my question.
a. I woke up to the explosion and went to the mines.
b. In the mines I had several conversations with Mariah, gave her presents and raised her Trust, Jealousy, Enjoyment and Passion to 15. This is the chapter's limit. Nevertheless, there was no way to raise her Lust.
c. I finished the dungeon, went back home. Talked to Val in the afternoon and waited.
d. I spoke to Mariah at night.
e. I spied on her in the shower for a last time.
f. I went to bed, the intimacy with her is LOW.
So, my question is: Is there anything different to do here?
