The team is astonished to learn that Na-rae, who joins the task force as a special advisor quant and a senior managing director at Plus General Insurance, is also Ki-jun's ex-ex-ex-wife, though the two seem surprisingly unfazed. As the team pairs up to gather data for the divorce insurance policy, Ki-jun takes Han-deul to an unexpected place seemingly unrelated to their research.

When Han-deul bumps into Ki-jun, weary from a run-in with his former brother-in-law, they begin to understand each other's demons of the past. Meanwhile, Na-rae and Jeon-man click and spark a mutual attraction, and Ah-young meets dancer and farmer Woong-sik on a blind date. However, as the task force gains momentum, they face a new challenge — rising divorce rates among their clientele.
