Comprehensive Manga: Becoming Yukino's Brother at the Beginning

Qingkong, who had just finished the college entrance examination, woke up and transformed into a newborn abandoned baby. Fortunately, he was adopted by Yukinoshita Ayano who was away, and officially became the eldest son of the Yukinoshita family - Yukinoshita Harukora. I thought that a powerful system would be waiting for me, but in the end, the system only sent me a starting gift pack, leaving a proficiency panel that could only check my progress, and I just ran away. There are no tasks, no rewards, and no points can be added. You can only see the growth progress of each skill with your own eyes. We are in a world that overlaps with various comics such as Harmono, Angel Next Door, and Kaguya-sama. He grew up with the young Yukinoshita Yukino. Rely on your talents and the visual proficiency panel to quietly polish yourself day after day and steadily improve your abilities. Under the calm daily life, countless anime characters appear one after another. As an older brother, he protects his sister and carves out his own path in life amidst the complex interpersonal relationships.
