Tin and Can cross a lot of each other's boundaries, but it's done in a way that doesn't bother me so much. Like, for one, it's very in character for them. Tin is usually calm and collected, and represses his emotions, and Can is the one thing to break that dam down. So Tin is feeling a flood of emotions that he really doesn't know how to control. Can, on the other hand, is very emotional, all the time, with everyone. And Tin is the one thing that amplifies those feelings, good or bad, in Can. Can is used to feeling a lot, but what he feels because of Tin - for Tin - is way beyond what he thought he could deal with. So they have a lot of push and pull to their relationship, sometimes literally, and they also want to make themselves vulnerable to that boundary crossing. They just keep getting it wrong because they want to be vulnerable on their own terms, obviously, not just when the other person wants it. And it's understandable that they keep getting it wrong because they're young, and this is the first time they're feeling all this stuff! They're just trying to figure it out!
