Hao's Links
Hao trusts his older brother completely and always tries to follow his advice. He also thinks of Fedele as his hero.
Fedele has a lot of love for his younger brother and only wants the best for him. It freaks him out that Hao is so cute and people are drawn to him. He is always torn between keeping his brother locked up safe and letting him be free to be happy.
Hao finds Lystal's attentions to be scary. He is never sure how far Lystal will go, and doesn't want to be taken advantage of.
Lystal flirts with Hao just to piss off Fedele. The opportunity doesn't come often, and therefore he goes all-in whenever he is alone with Hao. Which is very rarely, so they don't know each other very well.
Hao is terrified of Trygg. Everyone else is nice to him, and he doesn't really know how to deal with someone who is cold towards him. So he just doesn't talk to him beyond answering direct questions.
It annoys Trygg that Hao is babied all the time. He is never nice to Hao, and doesn't mind that Hao fears him. Trygg is the only member of the flock who resents carrying Hao's weight.
Hao has learned over the years that Nadeem will treat him better than even his brother does. Above anyone, Nadeem will comfort him and spoil him. And Hao absolutely loves Nadeem for this. While he feels really safe with Nadeem, Hao senses that he might be in danger of arousing a darker side in Nadeem. Despite being a fraidy-cat, Hao is drawn to this danger.
Nadeem has secret romantic feelings for Hao. And it's not just because Hao is cute and adorable, but Nadeem knows Hao in a way that no one else does. Hao always comes crying to Nadeem, and it has weakened Nadeem's heart towards the younger angel. Nadeem would easily give his life for Hao. But he wants to protect Hao from his secrets.
