Looking for a specific BL

I remember it being about two brothers and one is treated awfully by his mother (after their father passes) away and accused on being weird and creepy and being abused by her and the other is treated like a golden child but in the end (spoilers)






we find out that the well treated brother swapped the mother perception of the two boys using magic or spirits or something and he was actually the one who was weird, creepy and straight up nasty not the MC. And in the end it’s reversed and the MC is no longer abused by his mother
