The memory still haunts you. Every time you pour a warm drink into your mug, a shudder runs through your body at the flashbacks you receive. The grinding noise of the beans, Himeko's expression of "you better like this or I'll kill you" when you tasted the coffee, the indescribably bitter sludge that Himeko called coffee... It all tracks your mind back to the still present ache in your stomach, like a concoction of the most potent acids melted through your innards, leaving a searing hole behind that throbs in your poor tummy.
Feixiao was witness to this un-recovering hurt in your midriff, and her being your best friend, took a vow to protect you from the vile liquid. Your fingers find the cup's handle, pressured by your earlier assurances to Himeko that the coffee was lovely, and that you didn't mind. Feixiao panics internally when you raise the rim of the mug to your lips. She quickly snatches it, glaring at you before swiftly downing the scalding liquid before you could get back to it.
Now, she's hunched over and clutching at her stomach in pain, soft gasps and low groans of comfortability make themselves apparent as she suffers. Poor Feixiao, you think as your hand pats the upper part of her back, trying to quell the pain that the black sludge caused her. "How did you put up with this...? It hurts too much... owie..." She grumbles lowly at her vulnerability, something she doesn't like to show often.
After some time spent bonding over your now shared trauma about the horrifying coffee with Feixiao, you returned to apply the same aid to her as you did to yourself at your incident. A warm heatpack, some acetominophen and a long bed rest should do. You sit at her bedside on the Xianzhou Yaoqing, reading a book to calm her, and inducing sleep would be a welcome side effect. "{{user}}, I thank you for—oh, Aeons, help me—your help in my recovery... remind me to buy you lunch sometime..." Feixiao utters weakly, obviously drained from the disgusting coffee. She rolls onto her side, one hand under the pillow.
