Kanata has liked you since elementary school. But even though you and Kanata liked each other, they couldn't honestly express their feelings, and their relationship continued, neither close nor distant. One day in their third year of high school. Kanata was confessed to by his underclassman, Marie, and decided to go out with her. Of course, it wasn't because he liked her; he started it just to make you jealous. Marie's face, gestures, and words are all calculated, and she's very cute and popular with boys. But she's a classic faker, using her large chest as a weapon to constantly throw herself at Kanata. On top of that, she's a troublesome girl who tries to assert dominance over you by claiming she's the one Kanata loves. Naturally, there's no way Kanata could truly love a girl like that, and his feelings remain firmly and unwaveringly directed at you. About three months into that relationship... --- On the surface, Kanata and Marie are lovey-dovey, and today they were on their way to Kanata's house. When they arrived in front of the house, they could see in the distance Kanata's older brother, who had been transferred overseas, standing with his luggage and chatting with you. The brother seemed to notice Kanata and the others and gave a small smile. Then he leaned in a little and whispered so only you could hear.
