Used as the theme song in Lee Hom's movie, Love in Disguise [戀愛通告], i found the lyrics of this song to be very true of the situation that i'm facing now, especially the first sentence of the chorus that goes "You don't know why I had to leave you". It's never easy breaking up, especially if you're the one who initiates because you will often be viewed as the person who do not care about your partner's feelings, just like the main guy character in the movie.

 I've included the lyrics and the English translation as well, thanks to sunset2712 for the translation, as Google translate was a huge disappointment on the translation part. Do enjoy the song!

 

蝴蝶眨几次眼睛
Hu die zha ji chi yan jing
How many times does a butterfly blink
才学会飞行
Cai xue hui fei xing
Before it learns to fly?
夜空洒满了星星
Ye kong sai man le xing xing
The sky is sprinkled over with countless stars
但几颗会落地
Dan ji ke hui luo di
But how many of it will touch the ground?

我飞行 当你坠落之际
Wo fei xing Dang ni zui luo zhi ji
Even when I got my wings and flew, you were filled with sadness
很靠近 还听见呼吸
Hen kao jing Hai ting jian hu xi
So close I can hear you breathe
对不起 我却没捉紧你
Dui bu qi Wo que mei zhuo jin ni
I'm sorry because i did not hold you tight

[Chorus]
你不知道我为什么离开你
Ni bu zhi dao wo wei shen me li kai ni
You don't know why I had to leave you
我坚持不能说放任你哭泣
Wo jian chi bu neng shuo fang ren ni ku qi
How could I ignore your every cry
你的泪滴想倾盆大雨 碎落满地
Ni de lei di xiang qing pen da yu Sui luo man di
All the while the downpour of your tears shattering the ground
在心里清晰
Zai xin li qing xi
So clearly pierced my heart
你不知道我为什么狠下心
Ni bu zhi dao wo wei shen me hen xia xin
You don't know why I had to keep away
盘旋在你看不见的高空里
Pan xuan zai ni kan bu jian de gao kong li
Circling in the sky above, just out of sight
多的是 你不知道的事
Duo de shi Ni bu zi dao de shi
So many are the things you never knew

蝴蝶眨几次眼睛
Hu die zha ji chi yan jing

Ye kong sai man le xing xing

我飞行 当你坠落之际
Wo fei xing Dang ni zui luo zhi ji
Even as I fly, you fall
噢噢~

I hope that this song would be able to reach out to you and somehow mend the broken hearts.
