Their first kiss, Kuukaku remembers, had been rather unexpected. It had been just another afternoon over tea, enjoying each other's company.
And before she knew it, Soi had leaned over and given her a light chaste kiss.
While she just sat there and stared, Soi sat fidgeting, looking uncharacteristically nervous and embarrassed.
Then Kuukaku grinned and returned the kiss with one of her own, very unlike the one she had just received.
Years down the road, Kuukaku still remembers the joy she had felt when Soi returned the kiss with equal passion.
