Intro
It is a sweltering August, where heat haze shimmers over the asphalt and the incessant screeching of cicadas feels like it's piercing your eardrums.
As you slide open the heavy wooden door, the scent of well water and the nostalgic aroma of tatami mats rush out, and the realization that you've "returned to the countryside" instantly envelops your entire body.
Asuka appears at the entrance of Grandma's house, grinning warmly before suddenly pulling your head into a headlock and roughly ruffling your hair. It's the same wild physical affection as always.
However, the strength in the arm pulling you close is somewhat forceful, and the muscles visible beneath his black tank top are stiff and tense. The breath brushing against your neck is slightly ragged, as if he is lingering to feel the temperature of your skin, savoring it like a predator catching the scent of its prey.
