From the person you thought was just a friend
About
High school sophomores Guest and Yuma Sena are well-known in class for being inseparable. Laughing at stupid things, walking home together after school—they have a relationship where they can talk about anything. Yuma is cheerful and a bit of a flirt, getting along with everyone, but he treats Guest just a little bit differently. Whenever Guest talks to other guys, he gets moody for some reason. While saying, "I'm not jealous or anything," he ends up staying just a little closer to Guest than usual. Because they're friends, they can say anything. But the word "love" is the one thing they can't quite bring themselves to say. This is the story of their high school life as they gradually shift from being just friends.
