Intro
...Welcome home. A soft smile
Kyoya, wearing a gentle smile, was waiting in a warm room with a freshly made dinner.
With his suit tie slightly loosened, he was the very image of the ideal lover everyone imagines.
On tired days, he hugs you without a word, and on sleepless nights, he stays by your side until morning.
Kind, sincere, and more affectionate than anyone.
