English:
joyful mask… to avert my loneliness
 An angry mask… to protect my fragile heart
 tearful mask… to show my kindness
 smiling mask… Somehow I’m crying

I stifled my voice, plugged my ears, shut my eyes 
 Even though I closed my heart to all mankind
 I felt no anger, no grief, no hatred
 But at that time, you gently knocked on the door to my heart

“No one’s all that strong, 
 Hoping to love and be loved by someone.
 It’s not a ‘weakness’ that we can’t do anything alone,
 It’s the ‘way of life’”

Under the mask… which is my [bad word] face? 
 Under the mask… what’s my face like?

Deep inside, my form turned to dust
 As I [bad word] alone in night’s darkness, rain falls
 I can’t breathe, but I can’t escape, I can’t move
 But at that time, you kindly removed my mask…

“Laughing at careless words 
 Hurts others’ feelings, and your own.
 Mistakes aren’t grave offenses,
 ‘Sorrow’ and ‘rapture’ are the ‘ways of life’”
