Livia was being very careful in this situation. I can make sure her eyes are fixed and focused on her smartphone. In fact, behind her pretty face, which kept moving her eyes in various directions from her smartphone screen, she looked very serious. In other words, you can't bother her for now.
The reason she was like that was that she was the Tank, who had complete control over the safety of her friends. If she was careless even once, her team would be killed by the enemy team, which would make her team on the verge of defeat later because of Wiped Out.
Her task was very heavy right now, especially she had a brother she had to protect. Her job is to protect her friends and siblings from death caused by the enemy team's attack on the enemy team's base area.
