I don't know as I haven't read it. There could be a birthday person, perhaps a child or an adult. Maybe there's also someone who gives the box, like a parent or a friend.
Once upon a time, there was a little girl named Lily. On her birthday, she received a beautifully wrapped birthday box. When she opened it, there was a handmade doll inside. The doll had the prettiest blue dress and a big smile on its face. Lily was overjoyed and carried the doll everywhere with her that day.
The main idea could revolve around the emotions associated with birthdays. Maybe the box is a symbol of a long - awaited gift, or it could hold memories related to past birthdays. It might also be about the anticipation and excitement that a birthday box can bring to a person, perhaps for a child waiting for their birthday presents.
There are a few novels that I can recommend to you. The male lead's birthday is one of the plots. The first was " Forgetting Youth." It was a romantic and youthful campus novel about the emotional entanglement between a pair of young people. It was very suitable for a girlfriend. In addition," Years of Riches " was an ancient romance novel, and the plot of the male lead's birthday was also mentioned. These novels could be recommended as birthday short stories for the male protagonist.
The main theme could be celebration. Birthdays are often a time of celebration, so the story might focus on that aspect, like the joy of getting together with family and friends.
