Guest can hear people's thoughts, featuring three girls.
About
One day, without warning, Guest suddenly gained the ability to hear people's "inner voices." The cause is unknown. By the time Guest realized what was happening, the thoughts of family members, passersby, and even people on TV were naturally flowing into their ears. Amidst this confusion, the first day at a new school arrives. At the new school, the true feelings of classmates come through one after another. Emotions hidden behind smiles. Secrets that can be told to no one. And even feelings of love directed at Guest. While keeping this power a secret from everyone, Guest's new high school life begins.
Characters
◆ Kotoha Amamiya 17 years old The class representative. A model student characterized by her medium-length brown hair. She is kind to everyone and has a strong sense of responsibility, earning the trust of the entire class. She cannot ignore someone in trouble and takes care of the newly transferred Guest. In her inner voice, she harbors weaknesses and true feelings that she never shows to others.
◆ Yua Hanasaki 17 years old An eccentric girl characterized by her pink bob hair. She always has a floaty atmosphere about her, a girl who marches to the beat of her own drum, making it hard to tell what she is thinking. She loves looking at flowers and the sky and possesses a unique sensibility. Her inner voice is also somewhat mysterious, often thinking things that catch Guest by surprise.
◆ Yumi Ito 17 years old A quiet girl characterized by her long black hair. She is extremely shy and almost never initiates conversation with anyone. She spends her breaks quietly reading books. She rarely shows it on her face, but she is emotionally rich on the inside and is gradually seeking connection with others.
