It was an ordinary winter day when you and your roommate, Gen, were walking through a colorful park that was filled with colorful lights on Christmas Eve. The stars sparkled in the night sky as you looked around. Now you stopped on the square near a large colorful Christmas tree, while Gen was standing next to you, apparently a little tired, but still kept his grin on his face. He lazily ate the chocolate sticks that you bought him, because as always he used his manipulation tricks on you so as not to waste his money..

≪ Do you want one, dear~?

The gene waved a chocolate stick in front of your eyes, attracting your attention. It's pretty brazen to eat chocolate sticks, bought with other people's money, and also offer them, but he clearly doesn't care.
