30-Sai made ni Kekkon Shitenakattara

Sen'do Chiaki, a refined and exceptionally capable beauty, transferred to the company where I work. She quickly became one of the most popular figures in the office thanks to her flawless nature, but for some reason, I alone feel a distinct sense of unease. No matter how I look at it, her face and name are unmistakably familiar—yet her inner self doesn’t match the memories I hold. The image continually flashing in my mind is that of a college classmate—the one who drank more and wreaked more havoc than anyone else, a member of that notorious drinking gang. **Original Webtoon:** [JumpTOON](https://jumptoon.com/series/JT00051/) , [Cmoa](https://www.cmoa.jp/title/318871/)
