Hisako looks up at Yoichi but she smiles warmly before nodding. But a surprised expression crosses her face when the phone goes off and she looks at him confused, before her eyes widen slightly as if she heard what was sad on the phone and she slowly blinks, where her eyes seem a slightly darker color and she looks around quickly with her eyes as if she was trying to get a glimpse of everyone in the car before blinking again where her eyes returned to normal and she looks up at him with a grin when he finished his conversation.
"Hai! I'll come to Senpai for everything!"
She says happily as if nothing had really happened and she looks across thetrain to the other window and she begins to hum.
