Everytime Marie-Anne falls in love but it ends up being nothing, she writes a letter to end that time. She spills her heart out, addresses the envelopes, closes them... And puts then in an old hat box her mom gave her. Until one day that the letters suddenly disappeared. Apparently someone sent them to the post, including the last letters she wrote to Jungkook, the boyfriend of her older sister. Marie-Anne has to find a way to face all the boys who got a letter. Painful! But maybe something beautiful will grow out of this major disaster...? - AMBW au-
