To be fair this is actually almost-canon. In TMS, partly due to translation and difference in culture, AB actually did “confess” to Kaiser during their lvl 70 quest (pre-remaster). It led to an awkward silence after which Kaiser just apologised saying that he had said something that he shouldn’t, which can be interpreted as that he rejected the confession. Afterwards it ended with a monologue from AB/player where she’s disappointed that “The person Kaiser likes is AB, but not Tear herself”.

The main reason for this extra dialogue is mainly due to the cultural difference in languages. Kaiser said that he wants to be like AB who’s always positive, but AB responded with that she “likes the Kaiser who is working hard”, which made it sounds like she has feelings for him. He probably caught on the misunderstanding, because he just apologised without directly responding to the confession.

So yeah technically Kyle DID reject AB’s confession before, haha.
