Name webtoon

There was this webtoon I suddenly remembered reading ages ago. About these two brothers(twins?) one of them was gay and outed and one of the guy’s father and brother rejected him. So the gay guy moved out with his mom and the brother with his father. They both had red hair and the gay brother started dating someone and that guy mistook his brother for him. It had such a nice art style and story, I clearly remember the plot and character but just not the name plss help my fellow fujoshis ;_;;
