Both of them have a small argument which makes him more annoyed with her.

It also turns out that Darika's wedding gown designer, Suchawadee, used to date Anurut. Meanwhile, Pennueng and Pavinee's son, Nai, kills himself by jumping off a building. Further investigation reveals the involvement of Atom, Nai's girfriend and the fact that Nai had depression. Thuan attempts to recruit Suam to become a spy for keeping an eye on Sia Ha.
