The way Noa texts reminds me of girls I have talked to in the past. One would blow up my phone if I didn’t respond quick enough and the other would want to talk on the phone and text throughout the day. I didn’t mind with the first girl blowing up my phone, she was fun to talk to and I liked her. The second girl however irritated me. I liked my alone time just like Rihito, I do not like talking on the phone for hours.
So I admire Rihito setting a boundary, but I think Noa made a good point too. Sometimes, having someone to talk to about each other’s hobbies or a shared activity is really nice.
