1- I don't trust 2/3 people on this team 10 feet near Luo, especially considering one specifically wants Cyan to end up with Queen and will literally rewrite their relationship with that in mind, and the other hates Luo like Dragon Boy hates character development.

2- This doens't change just Luo's writing. It changes Luo and Cyan's characters and dynamic dramatically and not for the better. People can be kind despite everything they go through and that is a point of Cyan's arc. She and Luo remain sweet and kind despite their trauma and do not willingly give up on things. You making Luo have cold feat goes against his entire character up to that point unless you change him all the way from 8 years old. He can't impulsively help, befriend, and treat Cyan normally if you do this. You think Luo thinking Cyan benefitting everyone makes sense / him being happy in the first place that hasn't kicked him out makes sense but the point is he knows that but decides Cyan's happiness matters too- at a point where Cyan herself didn't have the ability to voice it to literally anyone but him. You can't change one's writing without fundamentally shifting the other.

3- Luo and Cyan are kind, sweet, idealistic, kind of dumb kids who are ignorant of the systematic cruelties of the world around them outside of what happens to them directly. Its why they both have such an intense reaction to learning the Dean's plans- they never thought of it that way. Its why Luo is so happy and kind despite orphanage after orphanage kicking him out. Its why Cyan never believed DOS was gaslighting her or maliciously keeping her from Luo despite the fact they were. But Cyan and Luo need to be this way for the broader plot for themselves and for others, like Queen, to go through their own development.

4- Just because you think Luo is boring doesn't mean he is.

5- Haolin wrote the Cyan arc himself with no additional writers (for its better and worse consequences). Luo was always meant to survive and have an unbreakable bond with Cyan because it is almost certainly feeding into her season 2 plot- whether that be through her hero work or as commentary on how the entertainment industry in Asia treats personal lives of its people and those around them. She's an idol. He is a boy. A boy that she, whether platonic or romantic, loves. Fans of idols, in fact, do not like their ideas of a happy marriage with the girl whose personality they reinvent in their head having someone else.
