Shiokaze to Ryuu no Sumika Sea Breeze and Dragon's Dwelling

Synopsis

After losing her father, Mizuka is taken in by her uncle and moves to Kagozaki, known as the "Dragon People Town," where she meets a boy named Tenshin, who also lives in her uncle's house. She tries to get closer to him, but he remains cold and distant. Could the fact that people call him a "human dragon" have anything to do with that? (Source: Lilac Scans)
