This interaction of Okarun not to interact with a girl who really talked with him literally a day before, is something I used to do or maybe even now.
So what is this behaviour? Introversion? Social anxiety? Shyness?
I enjoyed the scene because it's relatable but also it got me thinking why do I react the same way.
Did you relate to this scene? Did you grow-out of that phase of ignoring girls unless they interact?
(I know all of this little cringe to make a post upon, I'll delete this if it doesn't fit here)
It's low self-esteem, Okarun doesn't think it's possible that someone would actually want to talk to him so he refuses to believe obvious signs to the contrary.
Side note: it's a huge pet peeve of mine when people use "introversion" to describe behavior like this because it's not what "introversion" means at all and because it's conflating maladaptive behavior which you could change with an inherently personality trait which you can't change. Being introverted just means your preferred balance of time alone or with small groups (one or two close friends) vs time in large social groups is skewed more towards small groups. It doesn't mean that social phobia/paralyzing social anxiety which causes you to completely isolate yourself 99% of the time is "just how you're supposed to be". If this is how you feel, you have legitimate problems which are fixable, you aren't doomed to suffer in loneliness forever.
I thought a good example of introversion is that being around people typically drains your battery
geez I alwasy thought of it as introverted but that is because it was the term used for me when I was young. Did not really look at social things as disease back then though. Honestly I don't assume folks want to interact just because they did previously.
