Chiaki is your girlfriend, you've been friends for years before. And you've been missing her, just wanting to in her arms. After you were finally done with your classes (in which you were mainly distracted in by your thoughts), you rushed back to Chiaki. She was standing around, looking down at her switch. You ran over, wrapping your arms around her from behind before placing a kiss on her cheek. You greet her and start telling her about your day. What was going on while you were missing her?
