My theory, its because Ha-on forgot about it and if he forgotten the vow then the wish will not take on effect.
Remember how their baby dragon finally hatches? Didn't Ha-on said that he wish the egg would not hatch? But then it hatches after their reunion with ML? Its cause Ha-on forgot about it. And his present life, deep down he wanted the egg to hatch, unconsciously wishing it to be born and it was a success.
It did come true—at first, he felt nothing. However, after meeting and reuniting with ML, bits and pieces of his lost memories began to resurface. With every fragment that returned, his interest grew stronger. What started as simple curiosity soon turned into a desire to uncover more of his past and understand the emotions tied to those memories.
The baby dragon also played a part in awakening those emotions. Since intimacy could help the baby grow, it unknowingly influenced his desires and heightened his emotional responses. His growing arousal wasn't driven purely by lust; rather, it stemmed from a deep yearning to experience the emotions he had been deprived of for so long. In a way, he wanted to test those feelings, hoping they would help him reconnect with the parts of himself he had lost.
No no I'm sorry maybe I didn't explain myself right (english not my L1)
What I meant was that I THOUGHT the wish the dragon granted for Haon was not to feel anything
The flashback was Haon asking for it so I thought that dark spirits did that ...but when I saw he's waiting for the wish from the dragon, and since this one refused to granted him the returned to his home, I started to think this was the wish Haon ask for
Ion think so cuz he didnt "wish" smth like that for the baby dragon like he did w the ml
The baby simply didn't hatched before cuz it could hear that his mother didn't wanted him, so the baby dragon didn't hatched until uke started to want it
While the case w seme is that he has bound the promise that even heaven's can't break it so it's obvious they might have not seen eo for that lifetime but the seme did waited for uke in every lifetime so I'm confused if the power got reduce over time or did the seme break through it in some another life of uke cuz it's impossible to reverse it unless u sacrifice smth (I mean that's in most of the story plot cases)

How is he able to meet him/see him in present then (can I have some spoilers pls)
