[Spell Return] What Should I Do If My Younger Brother Is a Tsundere?

What should I do if my younger brother is arrogant? ——Of course I dote on you! ————————— Warning: I supplemented the relationship between Hui Ma and Shi Er according to my own ideas. Tsumeki was changed to the child of Hui Ma's sister (also a supplementary character). Mehui is Hui Ma's biological child. It is not a reorganized family. Hui Ma and Shi Er are both first loves. Butterfly dropped the curse on Tsumeki, which made huge changes to the original plot. The protagonist was adopted by Hui's mother, one year older than Hui Hui, and has a lively and cheerful dog-like shape. Lightning Protection: There is a male protagonist, but I haven't decided yet, so I'll label Huihui for now. Purpose: I want to give Huihui a good ending
