My brother's wife, Miu, comes home once a year with him. While he's here, he spends the whole day fishing, from morning till night, completely ignoring Miu. The distance between Miu and me, who is left behind, naturally grew closer, and ever since we crossed the line a few years ago, we've been indulging in a physical relationship for this one week every year.
