It’s not done yet. It has a novel in knoxt in english, and the following arcs is a lot lighter, the main story is five volumes. The novel is really good.
So vol 1 or s1 is the tragic story, vol 2-3 or s2 is bittersweet story (the healing arc), vol 4 is side story of both s2 and s3 (it’s sort of confusing.), s3 or vol 5 is the regret arc (the realization arc).
The novel has vol 6 which is a continuation of vol 1. But vol 6 is the IF story. According to spoilers, this is Rayfiel their omega son finds out about Aelock. So this is that story.
But there is another IF story, Aelock surviving that tragic event. He wakes up three months later.

HELPPP I WAS JUST LOOKING TO READ SOME LIGHT ANGST AND DIDN'T EXPECT IT TO BE THAT GOOD AND HEAVY TT
