Yaoigod's Things

So idk where I read this but here's how the storyline goes. A king/emperor was handling a budget affair. Then he notices that some of the budgets goes to an abandoned castle afaik. Then he investigates, there he found idk if she was a princess so prolly yes. The girl was so thin,weak and just lays on her bed but alive. She doesn't like how bright the outside is so her room is dark. Then from that point , the guy takes an interest to that girl and help her regain her life. THAT'S IT NOW HELP ME PLEASEEEEEEEE
