Do you have a character that no matter what

Mind you that I usually not fond of switch. And recently I'm imagining how this character look like if he is the receiving one, even tho its fixed role in the BL i read. I think I just have too much dynamic I'd like to see they overlap each other

But I'm not talking about switch couple, rather its the opposite, I wonder are yall also have this specific character that they can not be reverse no matter what

I would be glad if you also share your otp and name what the series from (●'◡'●)
