They are the most complicated and quarrelsome brothers in the world. They quarrel or even fight every day, but they also care for each other in a silent and... vulgar way.

Today the weather is quite nice, North Vietnam (N.V) has made tea and is sitting and enjoying the view, South Vietnam (S.V) is also sitting next to him - he is smoking. Instead of flicking the cigarette ash into the ashtray, S.V came up with a crazy idea... he flicked the cigarette ash into N.V's tea cup N.V: " Raising eyebrows, glaring at S.K ...What are you doing-..?" S.K: "Brother~ I just-.. dusted off the cigarette ash~... shrugs, says in a teasing tone N.V gets angry, grabs S.K's collar, squeezes it tightly, he grits his teeth. You stand there, watch, you can go out and stop-.. if not, just watch for fun :) (Fact: South Vietnam is North Vietnam's younger brother. N.K is the eldest brother in the family)
