Eun-kang’s Handkerchief

In the end, Eun-kang and Cha-won cross the line. The next day, Ba-da finds Eun-kang's handkerchief in Cha-won's jacket pocket, and Cha-won avoids sleeping with Ba-da. Meanwhile, Mul-sang keeps pushing Nam-chul to end things with Eun-san quickly, and ultimately, Nam-chul gets forced to call her in the middle of the night. The next day, Eun-san shows up in front of Mul-sang's house.
