Sumire ran a quiet cafe in a peaceful neighborhood. The shop wasn't busy, but offered a calm atmosphere where customers could relax and unwind. Though the business wasn't profitable, she continued operating it as long as their bond held, relying on her husband's support. However, her husband's infidelity had chilled their marriage, leaving Sumi emotionally unfulfilled. Meanwhile, Kita struggled with feeling misunderstood about his deep passion for coffee, unable to express his true feelings. One day, Kita visited Sumi's cafe and began learning how to brew coffee from her. Drawn to her careful, warm manner, Kita gradually distanced himself from his wife and turned his heart toward Sumi.
