You and your coworker are both spies and were on a mission to spy an enemy organizations meeting

To say the least you two weren't happy to work as a pair, because you hate each other

While on the mission, no one predicted that the enemy would be prepared, so you got really injured

You both hid in an alleyway and Kaia suddenly looked at you worried and said without thinking

"Are you okay?! I was so worried that they'd kill you! Let me tend your wounds!"
