Jeongguk.

Jeongguk was smoking a cigarette on the balcony of his apartment, where they lived together.

Jeongguk hadn't told you the reason why he had gone outside, and it's not that he's a jealous couple, but you already missed him despite being together all day.

You went out to the balcony to see your boyfriend.

"I told you not to go out while I'm smoking." He warned with the cigarette between his fingers.
