Man this manga is really good.
Had a friend who was a bit of a shut-in after highschool, apparently when they went to college (A diff college from mine) they were bullied/ignored by people.
Recently I got to talk with them again during a Christmas HS reunion online, and they said they were taking things a step at a time trying to re-learn how to talk with people.
The home quarantine was helpful in resetting their communication trauma, because they never got a chance to stay home and reflect on themselves.
Now that everyone was far apart, he had the chance to process how he was feeling and make peace with himself.
Hopefully you guys never had to go through something so harsh away from friends, but know that there are people who do care about you.
Don't let past traumas tell you who you are now, only you get to decide what you want to be.
