Who are her smiles for?

Ji-Won hastily brushed aside his downcast thoughts. Surely, the lack of rest was the reason for his current emotions.

'I guess it's been a long day and I am feeling tired. Yes, that surely must be it. Otherwise why would I be overcome by such troublesome feelings as these?' Ji-Won reasoned silently. 

"Let's go." Ji-Won said quietly, getting up to leave.

"Yes, you're right. We should go and say hi." Seo-Jun agreed, briskly getting up as well.

"Wait, what?! No, I meant..." Ji-Won began to speak frantically, but it was already too late. 

Before he could finish his sentence, he was already being pulled towards the small group by Seo-Jun. As his friend was clutching one of his arms, Ji-Won helplessly followed along, his hand still holding onto an unfinished egg.

Seo-Jun didn't wait to hear his friend's protests. Instead, he dragged Ji-Won after him as though he was running away from something terrible.
