thank you! and they’ve never been lovers, jay’s just always been that intensely loyal. exploring jay’s past (especially with just him and heeseung in the early days) is on my list of things to do, but the short version is that heeseung very much used isolation to his advantage with jay (who fought heeseung in the beginning like jungwon did but eventually broke), keeping him so sheltered away from the rest of the world to the point of jay’s thought process and opinions becoming exactly like heeseung’s; even after he learned about “normal vampire customs” years later, he’d been so warped by heeseung that he agreed with his Sire completely on his own. jake was much more willing right from the start because he was SO in love with heeseung and he’d do absolutely anything to for heeseung to continue loving him back. tldr; jay became “brainwashed” over time but was never in love with heeseung, loyal to a fault is just part of who he is.
