Kaeya Alberich is the owner of a small coffee shop, where he meets Diluc, a young man who can't speak. He falls in love immediately and it only takes a few weeks to become great friends, even though Kaeya wants more than that. One night, Diluc appears at his house, late at night, in the middle of a heavy rain and shivering with cold. He refuses to tell what happened and without being able to do much, Kaeya assures that he is welcome in his home as long as necessary, thus becoming roommates. The intimacy between them grows, along with Kaeya's hopes and fear of ruining everything. Things don't get any better when secrets and problems from both of their past arise to torment them once again. Now, more than ever, they have to trust each other and be the safe haven that the other needs to resolve all of this without their relationship collapsing completely.
