In the 10th episode of the TVN drama "Knowing Wife", which was broadcast on the 30th, Ji Sung (Cha Ju-hyuk) was placed in Danger, where he would divorce Kang Han-Na (Lee Hye-won).
Back in hospital, Ji Sung fought Kang Han-Na; Kang Han-Na was disappointed with Ji Sung and sent divorce papers and luggage to Ji Sung. Ji Sung tried to persuade Kang Han-Na, but hung up saying, "This is not what I'm doing." Ji Sung blamed himself. Park Hee-bon (Cha Ju-eun) agreed to divorce the two men. Han Ji-min (Seo Woo-jin) just looked at them.
Ji Sung was put in a Jang Seung-jo (Yoon Jong-hu) home; Ji Sung continued to struggle to turn Kang Han-Na's mind. Han Ji-min asked Ji Sung if he had fought Kang Han-Na because of him, and Ji Sung said he was blaming himself and did not care.
The company marathon was held; Han Ji-min continued to look back, worried about Ji Sung. When one participant heard that he had fallen into cardiac arrest, he worried that it might be Ji Sung, when Ji Sung appeared in front of Han Ji-min and asked, "What's going on?" Han Ji-min was suddenly in tears of relief and in confusion.
The mind-difficult Han Ji-min overdrinked at the party; Ji Sung and Han Ji-min talked at the playground. Han Ji-min, who was thrilled by Ji Sung, said: "One thing is not OK, I just don't know everything. I do not know conscience, guilt, and just one thing is that I like the deputy a lot. " Ji Sung said, "No, no," but Han Ji-min pulled Ji Sung and kissed him.
Ji Sung was in Danger to be divorced after taking care of Han Ji-min. Han Ji-min decided to date Jang Seung-jo for a month, but Ji Sung continued to care. Eventually, he got drunk and had an accident kissing married man Ji Sung with Confessions; between the two, he felt sorry for Jang Seung-jo, who knew nothing. In the trailer, the subway homeless made meaningful remarks; an exciting development is expected to unfold whether Ji Sung will be able to return to the past.
