hyunseung is an hitman, gets paid by killing people, hyuna find outs how he get the money as it cause a massive fight between the two, as he sleeps with other people hyuna goes to drinking, find out that they can not live without each other, as hyunseung gets another job instead getting money finds a "hand" which means his organization wants him dead. he goes after them on the last job which he doesn't tell hyuna because he wants to protect her, he than gets shoot but still uses everything in his power to drive her. as she is waiting for him. as his last breath was driving the car to her with a cigarette in his hand as he loves smoking...... I think I made that more complicated lol. but hope you guys understand hahahah, well that's my point of view and a few others lol
