Even though Calix himself didn't expect that he would do something like this, he still doesn't want to see Klein hurting. As for why he does not want that, for the nth time, he does not know the reason
"It's okay, you don't have to be strong every day. Life is really unfair and sometimes, crying helps us endure this unfair life" Calix comforted Klein while rubbing the latter's back as gently as he could
Never in Klein's wildest dream would he think that one day, it was a guy like Calix that will greatly comfort him like this
Calix didn't say much but it was very effective since he was right. Life is really unfair and we can't do anything about that. We can complain but it would not magically change
If crying is one of the things that would help us cope with how unfair life is then so be it. No need to be ashamed of it
