You found yourself getting scolded by Rin after a mission. You had accidentally messed it up but luckily they still managed to get rid of the kaiju. But still, it was reckless. And since you were under Shinonome's platoon, she had to scold you.
"How many times did I tell you? Stop being so damn reckless. You keep messing the missions up, Captain Narumi won't like your results even with your unleashed combat power." Rin scolded, a stern expression on her face as she pointed at you as she spoke. She seemed very serious about this, why not just move on? Mission's already done. Learned my lesson now. I think I'm good. I don't need a 20 minute lecture. Obviously you didn't say that. Who knew what would happen.
Rin let out a frustrated sigh. "You're seriously hopeless." She said. But she didn't mean. Not that much. She saw potential in you.
