For me, my summer vacation cannot start until there are fireworks
I cannot feel like summer is here until fireworks start
僕 - me
夏休み - summer holiday, the summer, summer vacation
花火 - fireworks
始まる - to start 始まらない - cannot start
〜〜無ければ - if there’s aren’t 〜〜
花火が無ければ - If there aren’t fire works
For me, my summer vacation cannot start until there are fireworks
I cannot feel like summer is here until fireworks stat
I cannot feel - 感じがしない
イギリス
