I agree that showing up at someone’s house like that (especially while live) is totally out of line. But I don’t think Reo’s intentions were malicious. Of course, it wasn’t right for him to keep showing up at Haru’s house, but he just wanted to talk. The way he went about it was wrong, though he was careful enough to record only audio, not video, so Haru’s address wouldn’t be exposed.
The main point is, he just wanted to talk but he handled it the wrong way. It was honestly pretty pathetic of Reo to chase after someone who clearly didn’t want to see him anymore. Most people with pride would’ve walked away or even resented Haru, but Reo didn’t. He just wanted to fix their friendship.

Haru better beg Reo for forgiveness. If my friend suddenly told me we should stop hanging out because "being with me is exhausting" and didn’t want to explain further, refused to stream with me but streamed with someone else instead, and kept ignoring me when I try to mend our friendship, I’d be pissed.
