Well, yes and no. First of all I'm sorry if I betrayed your expectations. I might remove the tag if it seems misleading (however its not that far into the story yet).

I put gentle because Alex wants to do her best to help and take care of Joe. Obviously this hasn't been really necessary so far although there was a bit in this chapter. I don't want to spoil much but, even as the shrinking continues, Alex doesn't have malicious intent. So it is gentle in that sense. But its not a completely gentle story becasue she's 1. very playful/aggressive in her ways although she doesn't mean anything by it, and 2. not very competent at taking care of others (immature).

She's definitely more oblivious. She would care if she really knew, but doesn't think of it that way and Joe is too timid to say anything yet.
