There's definitely one trope that annoys me the most (even more than forced love triangles) and it's:
NOBLE PROTAGONISTS!
(or how I also call it: "We have 4-6 Episodes left, what shall we do?"-Syndrome)
I get a headache the moment I hear something along the lines of "I should leave... so that he can have a happy life". Or when the lead remembers or learns that they've hurt the other person in the past (or have some weird disease or lied about something idk) and go: "Oh damn, I feel so guilty, how could he/she love me, I should just go and break up with her/him, we'll all be so much happier"
The Hell? I can guarantee that in literally NO drama I have ever watched, the decision to leave the other person, break their heart or keep a secret in order to "save" the other person, had a good outcome. NEVER. Therefore it gets annoying. It stands out to me as a viewer because we all know that trying to be "noble" in dramas always results in what you tried to avoid. So there's no surprise. We know what will happen.
I guess that's why it annoys me so, because it feels so forced and not like something a normal person would do.
I actually think it's not noble at all, I think it's pretty much taking "the easy way" out and purely egoistic. Leaving on your own is often easier than living with something or working something out together.
Not being noble is much harder. Depending on the situation you may have to grovel, beg for forgivness, learn to deal with some condition/disease and, most of all, you actually have to communicate with your S.O./love interest, truthfully and honest at that, which seems to be an impossible feat for most drama characters.
Sorry for the rant, it just annoys me so much and I wish there were more dramas with people who actually go for what they want/decide to take a chance on their possible happiness and COMMUNICATE, rather than give it all away for some altruistic reason.
