Make a reasonable retort

[player]Um, that does sound reasonable, but you've overlooked one crucial detail, Officer Ninomiya.
[Hana Ninomiya]Why don't you tell me what I've overlooked?
[player]Have you ever seen someone actively appear in front of the person they are following?
[Hana Ninomiya]Um... y-you're right. There's no reason for you to start talking to me...
Ninomiya folds her hands on her chest and frowns as if deep in thought. She sighs after a while.
[Hana Ninomiya]I'm sorry. I misunderstood you and said some nonsense.
After resolving this insignificant misunderstanding, we start to talk about things that we find concerning.
[player]From your tone, it sounds like someone really is following you.
[Hana Ninomiya]Yes. Recently, I get the feeling that someone is staring at me when I'm at school and other places. I even get the feeling that someone is looking at me through my window at home sometimes.
[Hana Ninomiya]...You probably think I'm being too sensitive, but I'm telling you the truth.
[player]No, that's not what I'm thinking. I wouldn't think much about it if it only happened once or twice, but it sounds like you've had this feeling many times and at various locations. I don't think you're imagining things.
[Hana Ninomiya]Thank you for believing me. Most people would become suspicious if they often feel like someone is watching them, let alone me.
[Hana Ninomiya]I'm usually an invisible person that everyone overlooks, so I get a very strong feeling when someone is looking at me.
[player]I see...
Who would follow Hana Ninomiya?
