I always had a simple life. Nothing about it was ever too extraordinary, but after my family's business went downhill and our necks sank in debts, the Choi Family helped us by lending us a huge loan. Eventually my family managed thank to their help, even our flower shop business grew a bit more, but that still wasn't enough to repay the given money.

Today they paid us a visit. By their expression I could tell that they came wanting something, I just didn't expect it to be me.
 My blood.

Their faces were trying to curl up warm smiles, but I could see underneath their masks the pain they carried in their hearts.

Their younger son was sick. His blood was destroying him and it need to be replaced. The only problem was that his blood type was extremely rare....so was mine. That made me the perfect donor. I was to live with them and and every week they would drain a certain amount of my blood and afterwards they would inject it in his veins. How could i refuse after all they did for my family?

"I agree."

The agreement was made and I was to move with them and be under their care and their son under my care.
