Takano is your boss, you work for him in the Emerald districts of Marukawa Shoten, in the 'shôjo manga' section..

You've been working for him for several months now, and even though he 'teased' you from time to time, you managed to keep your professionalism..despite that the 'teasing' was clearly some flirt like sudden kisses, little gentle touches and telling you that he loves you.. And one day, you were walking back home, late in the evening toward 11PM...
