Sakurai Sayuki seems to always look serious and nasty, although she's doesn't have that kind of personality at all. As a result, she seems reclusive and angry to her school-friends and tries to distance herself from them. As you may have figured, Sayuki is actually a sensitive girl that would happily fall in love. Because of this, she hopes for changes in high school and above all, hopes to find love. After being persuaded by her friends, she goes with them over the summer holidays to the beach. There she meets a mysterious guy who is not deterred from her appearance. Then, they talk and get to know each other. During this conversation, Sayuki smiles a lot and seems to reveal her true self. Before she leaves the beach, Sayuki finds out that he goes to her school. However, she soon finds out that Hagi (the mysterious guy), surprisingly, is one of her teachers!
