She said that three truth tells ago, too
She wasn't using this before, I can vouch for that. This is the first I've heard of this from her and it being a huge issue. Her relapsing was due to external factors in her life with work and more. This along with the pressure from mafia makes her, and anyone, resort to other means to just get relief.
So she's not sabotaging the game, she's trying to help herself cope.
Take my word for it. I trust Flower, and I hope you can trust me on this Kiku.
