Help me find a magna

Do you know this oneshot? I think it's shoujo. There was this girl who debuted as a model, but it wasn't going well. Anyway. There was this board on the station she usually goes to, and someone writes something along the line, "goodbye. I will die tomorrow" (he was trying to commit suicide). The next day, the board was filled with writings of people showing concern for the person who initially wrote the farewell message. It was words of encouragement, and it was really sweet (I think I cried). There was also a lawyer who left his contact details on the board. At the end of the day, the station officer was told to remove the board by his boss, and suddenly a man, who was the one who initially wrote on the board, appeared and cried and begged for the board not to be removed. It touched him so much. The girl saw all of that, and said she would take a picture and give him the photo instead as a replacement. Few years later, the girl becomes happier and stuff, and she was approached by the station officer who initially wanted to remove the board. He told her that the man who tried to commit suicide was actually left with a huge debt, that's why he wanted to die. He tried contacting the lawyer who left his contact number on the board, and his life gets better and he's a much happier person now.

It's an overall very heartwarming oneshot. I'd like to read it again. Sorry that the description is long! I was trying to be detailed as possible. Thanks!
