Kizon's manga / #full color bl(3)

Now I think there should be a story for the red haired dude and the brother

Is it really completed? It feels unfinished. If it is done then how is there no resolution to the dad problem or the ex-boyfriend on the sister? What will happen with that threat, will Simon go back to that school, or will he go to a different school? There are so many questions left unanswered here. It's has good art, has a good plot but just missed the mark.
