Does anybody know this story's title? I cant remember if it is a korean or japanese novel. The novel has an isekai-ed female character as the MC. Her reincarnated self has a brother. He was sent to a rural area because their mother was scared of him (because her father's power hurt her in the past and now MC's brother has that kind of power). So those who have that kind of power is only a descendant of royal or duke families. After the death of their parents, he came back to the main house to take over the family. At first he wanted to cut the MC off (not sure maybe because he resented the family) but MC knew this so she relied on him (maybe to win his brother's heart) and absolutely ignored the snake adults. Later the brother grew attached to her. Anyway. When a person of power is growing their power, it is called blooming or something? And they go crazy whenever their power is used. Apparently MC can calm those people with that kind of power. The king is fond of her too and was hoping to marry his son to her but he's not pushing it though. If anyone knows about it, please let me know!
