Soon-jae’s family decides to get their family picture taken to celebrate Joon-ee’s 100th day since birth. But of course things don’t turn out smoothly as they wish! Joon-ee pees on one of them, Soon-jae and Mun-hee fight over the passenger seat, Joon-ee’s parents Min-yong and Shin Ji is occupied quarrelling over their own matter, and Mun-hee and Hae-mi get sensitive over Joon-ha’s hair. Goodness! After all this, the picture is finally taken. However, Soon-jae is not happy about where the picture is hung… and Joon-ha even loses money selling his stock, which adds on to Soon-jae’s grumpy mood. In the meantime, Min-jeong is excited to begin her teaching career as her first day begins at Poong-pa High School. But things turn out to be rough from the beginning because of a pair of weird brothers in her class.
