What gets to me every damn time is Magnus’s face till the moment their lips touch. Look at how unsure he is, you can tell how he still doesn’t know if Alec is going to reject him. Look at how his pupils shift a little when they are finally face to face. His eyes are searching for Alec’s, he is trying to find the answer in them, trying to see what’s the upcoming conversation going to hold. Look at how his eyebrows shoot a tiny inch up just a breath before the kiss, utterly taken aback. This is why the kiss startles him so much his head jerks back by the sheer force of it; he wasn’t expecting it at all. He was expecting Alec to stop and talk to him.
The details are mindblowing. A fucking+ acting, Harry.
