Wouldn't it be crazy if Iruma is half demon and his other parent was the King in the demon world. Considering his grampie and other characters who devoted themselves to the previous King. Would sometimes see a glimpse of the past when Iruma did things, a not quite similar but kinda similar to their King.
Setting: Futuristic, they have this many weird planet they could live in.
It's BL and the MC is kinda spoiled brat.
Falls in love w/ male lead by talking to his father of wanting to marry ML.
Very scene: He pointed at ML that he wants him.
Fast forward ML is cold to him. MC's family got bankrupt?
ML being in military but almost never going home to MC.
I'm pretty sure it's this one
