About My Younger Brother Who Controls My Sister

It's weird, this is how I felt while reading this book. It's a wonderful feeling. I didn't have any guesses before reading this book. While reading, I felt that this might be an autobiographical novel about the harem. The sister who is controlled by the younger brother is arrogant and controlling Qingmei. Wu Moxi is unknown and weak. The plot guess is also that the arrogant loser. When Wu Moxi and the male protagonist are about to become mature, the male protagonist finds that he still relies more on his sister. In the end, he interacts with the younger sister who is controlled by the younger brother. The story of Xiang Chengquan suddenly turned around at the end of the first volume. What the hell, the elder sister simultaneously guided Qingmei and Wu Moxi to complete the Shura field and successfully trained the younger brother back to the sister control. I originally thought that the sister's indifference to Wu Moxi was because she believed that the younger brother, as the sister control, would definitely come back and manifested as the consciousness of the main palace. Only here did I realize that the elder sister is the big boss. It is now 2025-4-23. It is speculated that the ending may be a harem ending with four people together.

I want to know what the original title is [Blowing Kiss]
