From the Start, I Took In a Little Sister, and My Older Sister Got Jealous

I really hope that the male protagonist and his sister will be together. The other two are really uncomfortable to watch. If it's a harem, then it's the older sister and younger sister. If it's not a harem, then it's the younger sister. In the whole story, I just like the younger sister the most. I really like it and hope the author can take a good look at it. Please give me your opinion.

Overall, it's very good. I don't want the male protagonist to accept Xueying.

Who is the heroine? I hope they are sisters, so forget about Bai Xueying.

I really want to have such a domineering and strong brother! I'm urging you to update, and I look forward to more exciting things to come!
