The people standing outside the bunker had heard Dongwoo lashing out at Seojun. They were shocked, beyond shocked in fact. They never thought Dongwoo would have such a side to him.
And by the sound of his voice, they could tell he was deeply hurt and crying.
"Is he going to be okay?" Doha asked no one in particular.
With this, they were able to confirm that Dongwoo indeed held the twins dear in his heart. For whatever their relationship was, they did not know but they liked to believe he was being a good older brother.
After all, they were always going, 'Hyung, Hyung, how are you?' They were so nice and gullible around him. They were always smiling.
And though sometimes they got chills from being stared at for too long when talking to Dongwoo, they could all tell the twins had good intentions towards him and held him in high regard, this warranting that outburst earlier.
