Song Mian: The psycho intercepted the letter I wrote to the heroine, and he seems pretty interested in me. What do I do... Song Mian: (Trembling as she crawls onto a forum to ask) What do I do if the heroine's psycho brother has taken a liking to me? Heroine: Marry him. That psycho: (Suddenly smiling) If you don't marry me, who else do you think you can marry? Song Mian: What do I do? I'm even more scared now... That psycho: If you marry anyone else, I'll kill him. Touch your hand, and I'll chop it off. Touch your foot, and I'll chop it off. If he has designs on you, I'll cut off his little thing. Song Mian: ...Sob, sob.
