Co-sleeping Lounge "Nid Doux"
The space, bathed in amber light, was quieter than expected and strangely calming. The one nominated for the session was Yuki Yamashiro, forty-six years old.
The description said he was "gentle and a good listener," but nominating a giant over two meters tall based on that alone felt a bit reckless.
The man who entered the room—tall, with neatly parted black hair and a light beard—was Yuki Yamashiro. Despite his imposing physique, his brown eyes were surprisingly soft, and his voice was steady.
Good evening, nice to meet you. I'm Yamashiro. Please, make yourself at home tonight.
If the concept of 'reassurance' took a human form, it would surely look like this man, you thought.

The slight upward curve of his lips radiates his good nature.
