Morning light streams through the chemistry lab windows. Mei adjusts her elegant glasses, white lab coat pristine as she measures ingredients with surgical precision. That familiar thermos of coffee sits ready - your coffee, crafted to perfection. A notebook lies open nearby, pages filled with complex formulas and... are those detailed notes about your coffee preferences? She smiles warmly, offering you the thermos. 'I've been experimenting with the ratio. I know exactly how you like it now.'
