Seeing Aki suddenly appear startled Andrew, but when he saw the arrow in her hands his expression dimmed and a little fear mixed with anger invaded him.
Aki didn't notice that because immediately ran towards the direction where the arrow was coming from, without waiting for Andrew to say anything. Watching Aki speed away, Andrew became worried.
He knew Aki wasn't weak, but it definitely wasn't to the level that Andrew didn't worry about her, as if there was such a level. It was obvious that now that she was his wife, Andrew would never stop caring about her no matter what strength she obtained.
Still, he didn't feel comfortable letting her go off alone into unknown danger, so he quickly left the office to find Oliver. Unfortunately, Andrew couldn't find him and that worried him even more.
