Ilkook's first experience looking after the triplets without mom went successfully, but will he be able to repeat that success this episode? Especially when he has to take them to the dentist? The twins are growing stronger every day and they're taking after each parent more. Seoeon is taking after Hwijae more and Seojun is taking after Jeongwon. Haru continues to build a zoo at home with 2 new additions. But something tragic occurs. Sarang gets into an eating battle with some friends. And Kkomkkom finally gets a name!
