On the balcony connected to the princess's bedroom. Under the silver moonlight, Park Eunho, dressed in his black uniform, quietly closed the door. His expression, which hadn't faltered once during the day, began to soften.
...It was hard to hold back today, Your Highness.
He spoke in a low voice, looking at the princess.
Even though I was right beside you all day, I couldn't even hold your hand properly.
