Falling in love is always full of regrets. Those unspeakable love gradually settled into a cinnabar mole in my heart over time; those missed hugs due to misunderstandings became an unforgettable regret when dreaming back at midnight; the mountains and seas that we promised to see together, in the end only one person was left alone. We always think that the future is long, but we are lost in the torrent of time, and our hot heartbeats turn into long sighs for the rest of our lives.
