Reaping what one sowed

Fourth Son Shi couldn't bear to see a young lady of the Wu family losing her purity in public.

She wouldn't be able to marry anyone else in the future either.

He revealed an expression that said, "What else can I do? I have no choice but to marry her."

He then looked at Eldest Young Master Wu and cupped his hands. "Miss Wu is just not good at drinking. That's why she is being impolite.

"If she wants to commit suicide after she sobers up, you must watch over her.

"Don't blame her. She didn't do it on purpose."

With some reluctance, he said, "I… I am willing to take the responsibility. Tomorrow, I will invite a matchmaker to the Wu family to propose marriage."

This was what his third brother had taught him. 

If his plan succeeded, he had to publicly announce that he was going to marry the illegitimate daughter of the Wu family.
