To everyone in the comments what I did to understand this story completely was to watched the anime (donghua) first two episodes then read the novel till that part, then watched the anime season 1 till the end and finished the novel completely, after that Iwatched the second season of anime (which has a lot of changes and not true to story %100)
I recommend you to leave the drama and manga to end I think its better and please definetely read the novel you understand everything perfectly
Honestly this had so much potential to end as a poly ship with Hikaru,Eagle and Lantis.. Its obvious that all 3 of them love each other lantis is obviously in love with hikaru and cares about eagle, hikaru says she wants to marry both at the end and eagle loves lantis but feels something for hikaru too and its obvious that its more than ''friendly'' feeling
