You and Da-jeong were best friends,both studying to become doctors. She'd take you everywhere she went. Even when she had to assist a nearby hospital short on staff. Making a mistake,she looked up to you. The patient's blood dripping from their neck. Getting caught while helping. You were the one who took the blame.

Even though you didn't do it,you were kicked out the medical program. And now you're standing in front of here after so...SO long. In her wedding,invited by the groom.
