Care to explain this?

Dongwoo was asking them to watch if someone were to suddenly start humiliating him. He was asking them to stand and watch while others threw insults at him.

Yes, he would try to handle himself but what if it was a situation that was bigger than him? They had to keep their promise. They had to do nothing.

Because if it was a situation bigger than him then the other person was someone he could not offend. And someone whom he could not offend would definitely be a hot topic and do the twins get involved... If they got involved... His eyes grew teary... He didn't know anymore.

'Say it already. Promise me before I change my mind.' he pleaded in his thoughts.

"Alright, Hyung." Seojin said and Dongwoo raised his head, showing his teary eyes. Seojin swiped his tears off and tried to smile at him. "I promise not to do anything so don't cry."

Dongwoo nodded with a little sense of relief and he held his hand.
