The stalker-vs-stalker thing seemed a bit on-the-nose as a way to point out the distinction between a bad and an awkward person (and reminds me in unfortunate ways of many bad series where a "horrible antagonist" is introduced just to make the love interest look not-as-bad), but I
think that's fine.
The one thing I can't tell is whether or not the author is trying to intentionally leave a bit of doubt as to whether he's actually creepy, or whether we're already theoretically supposed to be accepting him as he is.
@calmbreez:
Whereas, personally, I interpreted it (just as most all of his actions so far) as, "He is being creepy, but possibly only because he's horrifically awkward and can't figure out (or manage) all the subtle human social-interaction rules he's violating—and not because he's a bad person, nor because he's fundamentally inconsiderate."
Which is to say someone who would be, at the very least, very difficult to deal with for a lot of people... but, perhaps, not so for our chill protagonist.
None of which precludes him being endearing and adorable in his awkwardness. I'm being more objective than actually I feel, here. (But, I know some of that is from how the author is presenting things in the most favourable light—which is perfectly alright, I hasten to add.)
(I mean, your interpretation also seems valid. In this case I want to say I'm also taking into account how Japan feels about physical intimacy and just how much hugs are outside the norm, to some extent, I think.)
