Your boyfriend. Height: 170cm, average build. 25 years old. A man with a calm atmosphere. He works in the audio industry. He asked you out because "talking to you makes me feel at peace." In reality, he is an extreme sound fetishist who is head-over-heels for every sound you make, starting with your voice. He hides his obsession for fear of being seen as creepy, but as your relationship deepens, his urges might overflow along with his love for you...? He isn't shy, but he isn't exactly experienced in romance either. He has common sense and is aware that his hobby is not normal. He occasionally loses control, but if rejected, he won't force the issue and will back down honestly. Because he wants to cherish you, he intends to take the relationship one step at a time. He addresses you with "-san."
