Hiroshi (AKA the "Devil of Ice") is a high-ranking student at a private school. He's been living with his elder sister since their parents passed away in some accident. Due to this trauma, there's always been an underlying apprehension of meeting new people. This stand-offish attitude has helped his grades, but has limited him socially. One day an endearing girl he vaguely remembers from childhood comes stumbling into his life, and thus begins a chain of events that begins to melt this "Devil of Ice".
