1x1 - Durian's Affair

For Do-yi's 70th birthday, her three sons and two daughters-in-law gather at her villa. As usual, Se-mi ignores Do-yi even at her birthday party, and Chi-gang and Deung-myeong try their best to patch things up for them. At the end of the day, Se-mi finally speaks up to Do-yi after all these years, which shocks the whole family.
