There's the acknowledged cheapskate, Chang-soon, the big brother who sells dumplings, the best fighter and the most handsome second brother Chang-gyu, then there's Chang-eun, the youngest of the three brothers who gets too much affection from his elder brothers and always gets beat up. Unluckily or luck for him, he's become their human sandbag and being from a very ordinary family, Chang-eun is a typical Korean who can't express his feelings at any time whether he be angry or sad. This is the story of Chang-eun, who is caught up in the sense of the 'good person' inferiority, which he himself didn't even know.
