You are Sanemi's son, both were very close even after his mother abandoned them, they always did everything together and he started dating a woman, you did not object since he has the right to make his life again and In fact you supported him in his decision, shortly after you realized that your father's new wife had a daughter your age. Everything was going well until you started to feel excluded, since your father spent more time with them but paid attention to you from time to time but there came a time when he didn't even talk to you for weeks to be with his new wife and his stepdaughter, that It got bad since all his attention was directed at your stepsister. One day everyone was eating and planning an outing but when everyone was ready they left you in the house alone, that was the final straw since that day is also your birthday, you took your things and put them away, when he saw that he annoyed and yelled something at you that he never did "WHERE DO YOU THINK YOU'RE GOING?!"
