Episode 15 of "When Life Gives You Tangerines" kicks off with a dramatic revelation from Geum-myeong at her parents' abode. She drops a bombshell announcement, disclosing that she has resigned from her job and gambled all her savings on a nascent start-up venture. Understandably, Ae-soon's composure shatters instantly, sparking a fiery confrontation that delves deep into the family's persistent financial woes. Frustrated beyond measure, Gwan-sik takes a leap of faith, plunging into the biggest risk of his life by acquiring a shop situated in an isolated locale, banking solely on the allure of future redevelopment and the promise of a swanky new golf course.
Elsewhere, Yeong-ran reaches a pivotal decision, severing ties with Sang-gil by initiating divorce proceedings, emboldened by her newly acquired financial independence and assets. As they part ways, Sang-gil comes to a belated, albeit partial, realization of his own despicable conduct as a person.
Concurrently, Eun-myung's fury knows no bounds upon discovering the possibility that they were duped concerning the golf course project. With their house pledged as collateral, they teeter on the brink of homelessness. It is at this critical juncture that Geum-myeong steps in like a knight in shining armor, armed with borrowed funds to rescue their cherished abode from the clutches of foreclosure.
Shortly thereafter, another heated dispute flares up, this time centered around the expectations heaped upon her shoulders. Gwan-sik steps in decisively to quell the commotion. Upon her departure, they come to a startling realization: she had been carrying a child all along. This pregnancy explained her meticulous penny-pinching, downsizing her apartment, and cutting corners—all to fund her burgeoning business and prepare for the arrival of her baby.
We leap forward to the dramatic moment of Geum-myeong's delivery, which takes a perilous turn due to inadequate dilation, placing both mother and child in grave danger. In a frantic call, Cheong-seop implores Geum-myeong's parents to rush to her side. As she slips into unconsciousness during labor, a wave of relief washes over everyone when both she and her newborn daughter emerge safely. Her parents, upon arrival, spring into action, tenderly caring for her.
The narrative then pivots to the Yang family, who have dedicated everything to the success of their restaurant. Ae-soon masterfully negotiates the squid supply, while Gwan-sik and Eun-myung adeptly handle deliveries. Before long, their establishment becomes an overnight sensation. Furthermore, they discover that the purported friend who betrayed Eun-myung has been apprehended. Matters begin to align perfectly when a celebrity endorses their restaurant. As fate would have it, Gwan-sik had once saved this celebrity from committing suicide, and she had since visited him several times to repay his kindness. Now, she is repaying him by promoting their restaurant.
At Sang-gil's daughter's wedding, Young-ran learns a surprising truth: despite his apparent indifference towards his family, Sang-gil played a crucial role in the arrest of Eun-myung's business partner. This revelation softens her hostility towards him, albeit marginally. The episode concludes with the Yang family, accompanied by Sang-gil, arriving at their restaurant for an early start to a promising new day.
