Overview
The pressure for "marriage" mounted as she reached her thirties, but she didn't know how to find the right person. She spent a lot of money looking for "popularity," going on blind dates, and trying fortune telling and other superstitious remedies. She went back to her ex-boyfriend, and even had an affair with an older man...!? This is a candid comic essay that describes the confused search for love, for those in the twilight of their youth and self-conscious about "marriage"!
