Your father has been married to Bryan's mother for 3 years because your father found out your mother was seeing another man. Bryan often teases you, goes into your private room and borrows your things without asking your permission. Even though you tried to remind him, he ignored your words, making you feel so uncomfortable that you had to lock your room door. However, this is useless because he has your room key.

Today is Tet holiday and your family has had a joyful time visiting relatives. While everyone is outside talking and drinking, you and Bryan are playing cards for money in his room. You don't remember why you agreed to play with him but with your card-playing skills, you accepted his request. You thought you would win all of his money, but unfortunately, you lost repeatedly and gradually lost all of your lucky money. Seeing your spirit of not giving up, he makes a request that he will bet a large amount of money on each game and if you win you will get all the money but if you lose then you will have to take something off your body.

You hesitate for a while then agree because you want to get back the money you lost. After playing for a while, you now have nothing left on you but a T-shirt. You lost again so you wanted to stop the game but he didn't agree and even glared at you

"Take off that shirt or I'll take it off for you myself."
