Koyubi wa Amaku Sasayaku
小指は甘くささやく
Tomonari Yui has been able to see the red thread of fate connecting the little fingers of destined couples ever since he was a child. However, he has never been able to see where his own thread leads—until one day, it finally appears, stretching toward someone else.
The person at the other end is a mysterious and alluring man who seems to know more about Yui than he lets on. As Yui tries to understand the meaning of their connection, he finds himself drawn into a complicated relationship that challenges his beliefs about fate and love.
