Indeed, and if you take into account her feelings at the start. She was quite literally on the verge of being classified as a yandere at times, it was only later, when the brakes got pumped hard and fast in response to Kirin, that she slowed down.Honestly, the actions themselves line up if you think about her personality and what she would end up doing if he suddenly changed his actions so aggressively.
I don't think the entire scene needs scrapped, the main thing I think it needs is a change in dialogue so it flows more in line with their personalities is all I think that needs to happen.
Her speedrunning the relationship thing actually makes sense before that. If this scene had occurred after the first beach event, I could see the issue with having it still be canon because it wouldn't flow well with her newly slowed personality.
