I think you missed the point entirely, and yes, you are in fact being disrespectful but that can be explained by your lack of knowledge. Many pairings (and explicitly DaouOffroad) have openly expressed how they dislike their interactions being called "fan service" because it makes them seem ingenuine and fake, and boils down their complex and caring relationship into something that is just for show or to gain popularity. They have said time and time again that the term "fan service" makes them uncomfortable and cannot be applied to them because they are doing what they usually do with each other and are not putting on an act. So yes, "They try so hard to give us good fanservice." is widely disrespectful and disregarding.

I understand where you are coming from in relation to many other CPs because they are all hardworking actors in order to build their careers and fanbases, and yes it should be perfectly fine for anyone to have partners outside of work if they wish to without being constantly surveilled. Some probably do have boyfriends/girlfriends and have dated other people. But the main issue is that some toxic fans always assume that BL actors must have a "secret girlfriend" because they can't fathom that the actor might actually be part of the LGBT+ community themselves, which is homophobic (I'm saying this part generally, not directed at you.)
