I'm looking for a oneshot that I believe is from a collection of short stories. It is either shoujo or josei and for sure is romance and tragedy (at least that chapter is). Overall theres a boy and a girl however they come across financial issues and the girl goes and asks her boyfriends employer or whatever for money but is rejected. She tells her boyfriend that their wishes were granted by his employer and begins to sell her body. One day her boyfriend sees her with one of her clients and she lies and says that she's just doing it for pocket money. Later on the boyfriend goes to see his employer and thank him and then learns the truth. The girl turns out to be terminally ill, and the two of them reconcile and get married. She dies in his arms and yeah. If anybody knows which manga this is please tell me ^_^. Thank you
