Qiao Yushan looked at Su Han and, upon hearing him say "I promise", couldn't help but feel a tremor in her heart.
He's going to guarantee it?
Qiao Yushan wasn't mocking Su Han for not having the capability; rather, she was touched by the realization that Su Han was willing to share and wanted to take on some of her burden.
It seemed that beneath her strong exterior, a fragile heart had suddenly found a pillar of support, though Qiao Yushan was well aware that Su Han couldn't actually help with business matters.
"Yeah, I believe you." Qiao Yushan smiled, brushing a stray lock of hair behind her ear, and took a deep breath before saying, "We might be busy until very late, are you sure you don't need to go back and rest?"
Su Han shook his head: "It's alright, I'm not sleepy."
He practiced martial arts all year round; even if he didn't sleep at night, it wouldn't affect him much. On the other hand, Qiao Yushan was clearly tired.
