The climax of She Was Pretty resolves both romantic entanglements and workplace mysteries:
- The Double Reveal (Episode 15): The drama's twin mysteries conclude with the revelation that the eccentric, unkempt reporter Kim Poong-ho is the conglomerate Chairman's son and Kim Ra-ra's nephew, while senior editor Kim Shin-hyuk unmasks himself as the globally renowned author TEN, providing an exclusive story that saves The Most from closing.
- Triangle Closure: Shin-hyuk bids a fond farewell to Hye-jin, dedicating his subsequent novel to "Jackson." Ha-ri confronts her past choices, declining unearned familial wealth to study hospitality management on her own merits.
- Ending & Epilogue: Rather than moving immediately to the US with Sung-joon, Hye-jin spends a year in the countryside authoring children's books. Sung-joon returns to marry her, and the final scene showcases their young daughter, proudly sporting her mother's natural curls and rosy cheeks.
