Here's a theory of why I think Iris joined the demigods: She probably lost all hope when she found out Lucas died and so when Lucas was mentioned you can tell sje looked upset. So she joined the demigods, to later betray them and accomplish Lucas's goal: to end the demigods.
but the thing is what if she did that but half way she gave up because the thought that lucas is dead came to her and she doesn't think she can do it without him. idk ╮( ̄▽ ̄)╭
Sung jinwoo would known that his father is alive, but sadly, we would never get to see the reunion between the two. Koonoia
(spoiler) . . . . . . . . That's not true, though. In the very end, the timeline is reset, and Jin-Woo gets to live happily with his family again - including his father.

Well in the original story he never meets his father, but yeah, he reverses time and lives happily with his family.
His father would eventually die trying to protect jinwoo from the bug, beast, and elf monarchs, but Jinwoo would eventually reverse time or sumthin like that.
Thanks for the clear translation
