No offence, but some of your favorite dramas ARE pretty toxic Though there are some who misuse the word, I’d say toxic refers to dramas where there’s unnecessary use of force without consent/emotional blackmail/stalking/excessive controlling/unnecessary, excessive measures in the name of jealousy/absolutely zero respect for private space and all of this justified by saying the two are “in love.”
Now, I wouldn’t call all wrist-grabbing “use of force” (though some people do, I see it as harmless and not really overpowering/controlling, they’re just stopping someone for sometime and usually let go when the character pushes them away - most of the time). But some dramas do cross the line and you can see the FL character is clearly uncomfortable. Force-kissing when the FL clearly doesn’t want it is definitely toxic.
Sure, many enjoy them and I wouldn’t stop anyone from watching, but that doesn’t excuse them from being toxic. It is what it is.
