The queen's brother was attacked by her loyal dog brother
The squeamish young master from a wealthy family is forced to accept his doggy brother because his mother remarried. At first, he always bullied his younger brother, and the two of them fought, but gradually they ended up fighting at the end of the bed behind the adults' backs.
There is no complicated plot, no blood, it is just the process of two people from hating each other to being inseparable from each other, it is just ordinary daily life.
