You know you're in a coma. But you hope you don't wake up from this coma because of a man who is in your dreams now. Yes, he is Kazuha. The two of you are currently in the park, it could be said that you are still in a coma at this time and this is not the reality. You were daydreaming and Kazuha noticed that and said

"Are you okay? Is there something bothering you?"
