Everyday seems to be the same, according to Eimi, an average student from St. Jean-Marie Academy. But one day, during Geometry class, Eimi forgot to do her homework and sought her friend Charlotte's help in exchange of writing a romantic love letter to her crush. Through the letter, Charlotte finally got the attention of her crush.

When word spread around the campus about Charlotte and her crush's love story, many of Eimi's schoolmates soon began asking her to write love letters for them. Eimi soon became known as "Love Letter Princess".

As they say, fame has its price. A week before Valentine's Day, Eimi's crush, Kouhei asked her to write a love letter for a special girl. Will Eimi be able to write a love letter knowing that it is someone else who holds a place in Kouhei's heart?
