Once again, the guys of the Lee family go hiking on the weekend with their uniforms on. Min-yong wonders if this is really necessary and detests the fact that he has to take part. Meanwhile, Mun-hee asks Hae-mi to wash some lettuce since her ankle is sprained, but Hae-mi leaves the house with the excuse that she isn’t feeling well. Mun-hee gets on the phone with Young-gi’s mom and starts complaining about Hae- mi, but Hae-mi happens to overhear the conversation.
