18 hours late to this HELL i'm sorry.
honestly i didn't really think much about the ship when i joined the fandom because, to me, on the surface, they just looked like the typical "opposites attract" ship since they seem to be so different in many ways. but as i've analyzed their personalities and i think that is a huge part of their dynamic, i do think they know and understand each other perfectly. intak is very respectful with jiung's boundaries and never crosses the line with him since he wants him to feel comfortable, he's always been like that even since the early days. i think that's part of the reason why they've grown so close to each other to the point of calling themselves best friends before debut since they spent so much time together learning about their differences and respecting them. i also think that comfort is the reason why intak also knows that when they're meant to do fanservice during fan events and such with jiung, he knows he won't mind and is more than happy to get close to him when he has the chance, since jiung will let him because he rarely says no to doing fanservice. their bond is strong to the point you can catch them staring fondly at each other at times, acting like they're nothing special, like they're just two guys who enjoy being around each other. their bond is so strong that jiung and intak gravitate towards the other whenever they laugh, especially if they're sitting together, since their first instinct is to share the happiness with someone they've spent such a long time with and that they already have happy memories with.

tldr; i love their dynamic where they're different but they understand each other and care/respect one another. intak likes allowing jiung to be comfortable (+ since he's sensitive) and jiung appreciates that effort a lot, so he reciprocates by having fun with him and showing a more energetic personality to adapt to intak's.
