"Pop Princesses' Secret Serenade"

About this Scenario

What is some good story points to make this storyline interesting. Or just an outline for this hualian fic: hua cheng and xie lian(both female in the modern day for this au) are both pop stars with opposite styles(xl is cutesy/pop, like twice, new jeans)(hc is more r&b rock pop, think black pink, or katseye) they are both globally recognized(but are most popular in their home countries like a lot of K-pop groups irl) xl is a little bigger than hc because xl has been performing longer and is iconic but hc is still very popular. However, what the public doesn’t know is that they are married. They have been in a relationship for years but have hidden it from the public. In public hc is like a baddie goth fashion superstar with kickass songs the internet eats up and xl is like the countries angel princess, she has an innocent pure image but has baddass lyrics with fun girly beats and vocals. But secretly they are passionately in love and obsessed with each other and 3 years married(though no one but their close friends know). Their companies despise their love, partly because they don’t understand lesbian romance and partly so they can preserve xl’s image as “pure”. But they will never leave each other and always support one another. They work hard, but at home it’s just domestic bliss, though they are pretty sexually active with each other. Shi qingxuan is another pop star that’s bffs with xl, they often hang out and sqx fills xl up on all of the gosspic of the world. Sqx is dating he xuan, a big business man that works in the music industry hx is good friends with hc but they would never admit they are friends out loud. Any way what could be a story outline? I don’t want a lot of angst, though there can be drama, I rlly love stories where hc and xl have kids so maybe xl gets pregnant or smth, like some women can have kids together in this world but it’s rare or smth
