Mai (Mikie Hara) has suffered a great wound to her face in an accident. It is a minor injury, but the doctor says, "If you are exposed to UV light before it cures, a scar will be left". To hide the wound, Mai puts a large bandage on her face and comes to avoid the public eye. Takuya (Ren Yagami), who helped Mai at the time of the accident, tries to cheer her up. He had been in love with Mai from before, but Mai takes his kindness as pity and cannot accept his love honestly. With encouragement from her colleague Aki (Haruna Kojima), little by little the ice in her mind melts. Then Aki decides to be a cupid of love at last.
When Mai regains her honesty under the sun, will she be united in love with Takuya?
