Please help, looking for a certain mini drama..

Hi! 

I recently watched a Chinese drama (I believe it was a historical mini drama) and i only remember the following..

1. ML was crown prince
2. he had an older brother
3. The older brother repeatedly tried to frame his brother to become crown prince, BUT he actually didn’t want to hurt the younger one
4. ML knew about the doings of his older bro and good heartedly accepted them / didn’t really mind them
5. someone else (the stepmother? Or the helper of the older brother?) wanted to kill ML and the older brother good mad, cause as I said, overall, they had a pretty good siblings relationship
6. there was a FL and romance, but I can’t remember more X_X

I even commented about the brothers, cause it was so cute.. but I just can’t remember the name of the drama anymore. Does it ring a bell for anyone?  I’d really appreciate your help! 

Is it any of these? No? Try changing the search terms,

might be Chinese drama Royal Nirvana or Princess Wei Young or the Korean drama Queen for Seven Days,, they are not mini drama though

Thanks for trying to help, as postet above, I already found it, it was The Deliberations of Love :)
