I hear you... I'm curious to see how they'll explain it away and/or spin it for redemption once SSY becomes privy…
When you pitch a story, you usually don't start with the character's background but with a hook. I think their relationship was built good for their dynamic. Hua Yong instantly fell in love with SSY 15 years ago and had his entire life revolve around him which was a solid foundation (or maybe I've read too much dark romance and this is so messy in the most unhinged way) and SSY fell in love with Hua Yong throughout the series. In the first episode, he was never in love with him but His Yong was just his favourite ‘omega’ and he had a soft spot for him. As an Alpha, he started being protective and possessive because he's an S-Alpha, Hua Yong is his favourite omega, and considering the power dynamic ... He feels the need to be dominant.
He started from having a soft spot for him, (And mind you, SSY had a female Omega who kept him occupied during his rut but he ended up brushing her off), then went to liking Hua Yong until he realized he really loved him (which was during the earthquake if not mistaken.)
The script was written a bit poorly since they excluded many important points but let's not speak on their relationship foundation.
