The witnesses E, as the wife of the Defendant C, participated in the instant agreement at the time of the formation of the agreement, and as the Defendants complaining of the difficult circumstances that the Defendant B did not have, at that time, faithfully performed, paid 35 million won when D, 75 million won was faithfully performed.
