Everyone knows that Si Nan is an outstanding student and a perfect straight-A. Si Nan's side of the family is not well known to others, but he does have a side that's not known to anyone else. He's pretty, smart, and handsome, but his side isn't as well known as his brother's. He tells his brother that he's going to sing at the New Year's Eve party with his auntie, but Si Nan doesn't want to sing, because his singing is too serious. Everyone gets up to sing a good old-fashioned good luck song, and Si Nan says that he can't sing because his voice is so bad. Everyone agrees that he shouldn't be singing, and they all have a good time singing together. When Si Nan gets up, he tells everyone that he hasn't seen his sister for an hour. He worries that she's been looking for him, and he plans to go find her.
