Episodes 19 & 20 are an emotional roller coaster. The lives of Do Kyung,
Ji An, Ji Soo and their families are turned upside down. First the goodbye kiss, the awkwardness of both Do Kyung and Ji An the day after, the brutal behaviour of Do Kyung towards Ji An when she had asked for a meeting, but wasn’t able to say the reason for her request because of this, Ji An doing the confession alone and the aftermath resulting in Ji Soo slapping
Ji An in her face!
