Substitute Sisters: Wrong Marriage, Right Love

My sister and I have been engaged in marriage since we were children.

However, we engaged in two different types of man. It could be said that my sister engaged to a top-class person, while I just engaged to an idiot.

But a tragedy befell my sister. On her wedding day, a top fan used a bottle of sulfuric acid to destroy my sister's face, turning her into a monster.

Besides, the idiot I married recovered his sanity three months later and became a maniac who doted on his wife.
