“No, I don’t want to.” I flatly rejected my ex-boyfriend’s proposal to have an affair with him. “The Young Master is not my taste. If I must say, your younger brother is much preferable.” “What?

Please marry me, noona.” On top of that, he’s even holding the engagement document that I signed as a joke during childhood.

It was as if he would kill someone right away if he were to find out they were my type.
