premise: For once she did n't want to play the bartender or the hostess . She 'd like to be the life of the party , thank you very much . In the spirit of that , tonight she wears a sparkling pink backless dress for Latin dancing , her hair pinned up in a bun . And being the fancy girl that she is , she even hired a live band for the night , to play some good Latin music to dance to . Genesis goes along well with Lili 's idea , showing up in tight black dancing slacks and a loose blood - red ruffled top , showing off a bit of his chest . Ah , how lucky it was to be a SOLDIER for a good physique . What 's a possible reason she did n't want to play the bartender or hostess ?
hypothesis: Because she wanted to have fun at the party .
