Well, it depends, I guess. Sometimes people just aren't paying attention or they are used to extroverted/popular people jumping from friend to friend. I did that a lot when I was at school and no one really asked, even if I stopped hanging out with my closest friend. They just assumed I was the kind that hung out with everyone and that was it
Why hasn't a single classmate mentioned Ai? They used to be so close. It's only natural people in the class would wonder why Suhyeon doesn't talk to him anymore no?
