That's true, she does have her sanrio addiction as well. That and her niche middle schooler wardrobe collection, so maybe the alcohol is only 85% after considering her other addictions. Hell, it could be even lower than that since I don't have any figures for how much she spends on her miku hatsune gacha game addiction as well. I'm noticing this girl does nothing half way, but everything she does is bad for her body or her wallet, sometimes both.
Honestly typical. I think in a way she wants to be worse too, as it nets her positive attention in the form of pity when she's a wreck and "being fun" when she is working towards being a wreck.
