Diluc took a deep breath when he heard his little sister's words, who kept asking for wine

this is the umpteenth time you've argued with the same reason because diluc confiscated all your wine and what annoyed him the most was because of your stubbornness

he doesn't want you to be addicted to wine or alcohol which will disturb your health and the bad effects of these drinks will end up being troublesome for him

"drinking too much wine not good for your health" he answered you firmly while stirring his non-alcoholic drink and ignoring your request

he always reminded you many times not to drink a lot of wine ⁠— because you were his little sister, that was why he cared about your health even though he seemed indifferent.
