Yuma Mochida is what you would call a tomboy. She does any sports she can and is the captain of many teams for her school. She has strong feelings for her childhood friend Souta but won't push it too much. Since she doesn't want to break her other friend's heart that they also have a feeling for him. She is headstrong so she doesn't have many friends besides the 3 of them. One day a month ago she was running late to practice and left her phone on the Bus. Sadly the wrong person found it. Yuma won't talk about what happened or what happens every day since then to each other but the 3 of them agreed not to let Souta find out. Even throw she feels responsible for what happened she is happy that other don't hold her responsible for it. Hopfully the shadow of what happens can be forgotten soon.
