[Verse 1: Yeonjun, Huening Kai]No one knows about that winterThe endless worries and shaking heartbeatFeeling blue through those frigid blue daysI remember how you embraced me with your warmthIt's just like magic, you're the only oneYou changed my horn into the crownNow all my days and nightsA spring breeze washes through when you call out my name

[Chorus: Taehyun, Yeonjun]When we're high, when we're lowYou're always by my sideAll my youthIs filled with your warmthIn the warmth of your soft sighsMy once so chilly worldIt blooms into spring at lastMy blue spring

[Verse 2: Soobin, Taehyun, Beomgyu, Yeonjun]Flowers that bloom from blue (Flowers)In our warmest hours (Hours)Our promise to be together (Promise)After a long winterYou came to me as springI'll be with you every momentYou said, "we're destiny"Without each other, can't imagine it

[Chorus: Yeonjun, Huening Kai]When we're high, when we're lowYou're always by my sideAll my youthIs filled with your warmthIn the warmth of your soft sighsMy once so chilly worldIt blooms into spring at lastMy blue spring
