Xinyi has been afraid of being disliked by others since she was a child, so she has always tried hard to be nice to others. Whenever someone gives her a little attention, she easily develops feelings for them. Everyone calls her "Sticky Note Girl" because when people need her, they can just tear her off and use her, and when they don't need her, they can throw her away carelessly. However, she is actually a sentimental fool. Her lack of assertiveness often makes her soft-hearted when she needs to make decisions. One day, in order to win back her philandering boyfriend Gucci, she spent a lot of money on a cruise called the "Love Boat". Unexpectedly, she went into the wrong room by mistake and woke up to find herself having had a one-night stand with a stranger. Moreover, she also discovered that her boyfriend Gucci had been cheating on her with a wealthy widow and left her behind. This came as a devastating blow to her.
