When You Come Into My Heart (그대 내맘에 들어오면)

南韓電影卑劣街頭裏，趙寅成因母親多病而退學，由酒吧侍應變成黑社會小混混，為了出人頭地而殺死自己的「大佬」，最後他的手下亦為同樣理由而殺了他。

電影中，趙重遇初戀女友，當時對方在卡拉ok唱了這首由Jo DukBae (조덕배) 唱的When You Come into My Heart，後來趙到卡拉ok時，想念她而再唱。

因爲歌曲大受歡迎，先後有多為男歌手重唱，包括Jo Sung Mo 和Sung Si Kyung。

[chorus]的意思是：
I would run ...
I would fly ...
If you come into my heart

Even if I wouldn't run like a child
Even if I wouldn't go chasing butterfly
Like so, I'd remain by your side a long long while
And rush around you like a river
