Eun sang says hi. She asks if he studies a lot. She didn’t so she is worried. Tan asks, is it really you? Eun sang says she wanted to ask before, but why is his face like that? What happened. Tan says you left. Eun sang replies, "I came back. I won’t leave. First I will take exam. Then I will make any excuse. I still stay here. Besides you." Tan hugs her tight.
