鋼琴聲音響起，一首《firework》的音樂響起，同時一個甜美動人的歌聲也響著起來。
do you ever feel like a plastic bag/drifting through the wind， wanting to start again?/do you ever feel， feel so paper thin/like a house of cards， one blow from caving in?
伴隨著動人的歌曲響起，身穿黑色長裙，如同瀑布一般的直線長發傾瀉而下，披灑在她的麵龐上。顧夢晨戴著麵具唱著歌，從剛才葉帆走出的地方走了出來，從葉帆身邊圍繞著鋼琴一圈，來到舞台中央。她的舉動成了全場的焦點，全場的注意力漸漸地不在葉帆上了，幾乎都在注視著夢晨。
do you ever feel already buried deep six feet under?/screams but no one seems to hear a thing/do you know that there's still a chance for you/'cause there's a spark in you?/you just gotta ignite the light and let it shine/just own the night like the 4th of july
歌曲還在繼續，夢晨對台下的情況保持一副鎮定自若的樣子，仿佛那些目光都不存在，她站在舞台的中央，身後有葉帆伴奏，她整個人進入了空靈的狀態。聲音也隨著葉帆彈出的節奏，變得響亮動人。
'cause， baby， you're a firework/come on， 'em what you're worth/make 'em go，“aah， aah， aah“/as you shoot across the sky-y-y/baby， you're a firework
歌曲唱到這一段，坐在第一排的韓羽他們都站起身呐喊起來，緊接著全場都歡呼起來。最激動的要屬計算機係那邊的。全部人包括小萱和惜音她們，眼睛都看著葉帆和顧夢晨表演。
come on， let your colours burst/make 'em go，“aah， aah， aah“/you're gonna leave 'em all in awe， awe， awe
夢晨伸出左手對著台下的第一排的林鑫他們大四男生招了招手，同時做出了√√√的手勢。台下的大四男生看見了夢晨的手勢，眼睛都看了看彼此，立刻直接叢台上躍起，來到表演舞台，來到顧夢晨身旁成群跳起了舞來。
you don't have to feel like a wasted space/you're original， cannot be replaced/if you only knew what the future holds/after a hurricane comes a rainbow/maybe a reason why all the doors are closed/so you could open one that leads you to the perfect road/like a lightning bolt， your heart will glow/and when it's time you'll know/you just gotta ignite the light and let it shine/just own the night like the 4th of july
