Na-rin could not easily accept the breakup with her long-time lover Eun-chan after being informed of the sudden breakup, so she wants to have a one-month grace period for Eun-chan's feelings to return. "Love always ends out of the blue, and parting is always difficult." But as Na-rin jumps into the album production project for "History of Love," she's in a position to think about "breakup" more than anyone else. Can Na-rin find the purpose of the breakup that she has postponed?
