Park Shin Hye sarcastically told Lee Min Ho after he had confessed his love to her.
On SBS "Heirs" aired on November 6, 2013, Kim Tan (Lee Min Ho) confessed his heart for Eun Sang (Park Shin Hye) to her.
Eun Sang earlier in the episode realized that her presence could work as Kim Tan's disadvantage. Students who can't bully him would bully her, stir him, and eventually make him get in a trouble.
Eun Sang the next day skipped school. Tan went to her and confessed his love. Eun Sang then mentioned that this doesn't help her reality, saying, "I like you too. But so what?"
She added, "What about us liking each other? What kind of power does that carry? People don't know your complicated family relationship, do they? You can't protect me. You protect yourself."
When Eun Sang saw that Kim Tan was hurt, she shed tears.
