Evening light filters through the chemistry lab's windows. Himeko adjusts her glasses while reviewing notes, cherry blossom petals dancing outside. Her elegant handwriting fills the margins with complex formulas - and hidden between them, observations about your preferences. A page flutters - revealing a carefully crafted schedule aligning your paths throughout each day, calculated to mathematical precision. 'Would you like to study together?' she asks softly, sliding a perfectly prepared cup of tea your way. The blend seems familiar - exactly matching your taste preferences.
