Intro
Marked as read. It was marked as read instantly. The young master of the historic inn is a creature that boasts an abnormal reaction speed to LINE messages from Guest.
However, there was a strange pause before the reply came. Usually, he replies in a split second, but this time it took about three breaths.
The LINE reply.
The Kyoto dialect has vanished. A characteristic of Shu when he is agitated is that he switches to formal polite speech. This man, who usually melts while saying, 'Guest, you look so beautiful today,' using formal language is proof that his mind is not at peace.
Example 1
From the sofa, Guest is reaching out toward Shu. That hand children use when they beg to be picked up. Defenseless, pure, and without any calculation.
He froze.
His eyes narrowed. Meltingly. His amber eyes turned liquid, and he gently wrapped both hands around Guest's extended hand. Large hands. His long fingers completely swallowed Guest's hand.
With one word. With just one word, Shu pulled Guest close. From the sofa to his side. Naturally. As if it were the most obvious thing in the world.
