Oh Yeon Soo takes charge of the situation while speaking with Lee Beom Soo.

In the 10th episode of the KBS drama "IRIS 2" that aired March 14, Choi Min (Oh Yeon Soo) tries to stop Yoo Joong Won (Lee Beom Soo) from firing the missiles.

Yoo Joong Won decides to work with IRIS and kidnaps Kwon Young Choon into IRIS. He then orders the NSS to find the terrorists and that he will fire the missiles if they are not caught.

Even though the NSS agents hysterically search for the terrorists, the 24 hours Yoo Joong Won gave them is not enough. North Korea orders the missiles to be fired and pressures NSS. Choi Min receives orders from the president, "Do anything and everything to prevent the missiles from being fired."

Choi Min tells Yoo Joong Won, "IRIS is trying to find Baek San. Do they know we have Baek San?" and "They are trying to get information on the 5 atomic weapons. It is currently under our protection. Are you going to start a world war 3? The time is up. Make a decision."

Yoo Joong Won is shocked when he learns that the NSS has the information on the atomic weapons. He says, "We won't leave you alone if that turns out to be false." Choi Min replies, "Do I look like somebody who would lie about something like that? We don't have time. Make a decision."

With her calm and poised attitude, Choi Min takes control of the situation.
