My heart is like a bomb that could explode at any time because I'm too sad. His eyes were filled with endless sadness and loss, as if the whole world had lost its color. Seeing his disappointed eyes, my heart also trembled because I deeply knew how sad he was. Her tears kept falling to the ground like broken beads, making her look even more helpless and sad. My heart hurts like it's been hit by a hammer because I'm too sad. His voice was low and hoarse, as if it was difficult to breathe because he was too sad. When I saw his disappointed expression, my heart couldn't help but tremble because I knew how sad he was. When I saw him with that girl, my heart felt like it had been hit by an invisible hand. Her eyes were filled with pain and despair, as if the whole world had lost its color because she was too sad. My heart can't bear more pain and sorrow because I'm too sad.
