@henta1lover0 well considering it's likely still the original Japanese underneath it, with some additional context of that split second flashback, I'd hazard a guess it's something like " She likes him but, doesn't think he'll forgive her yet" or "She likes him but, isn't willing to admit it yet".
Basically it's either guilt for how their relationship started, with her basically raping him, or something to do with his past and the girl he remembered that is tied to his damaged self confidence.
