what, and you too disliked at start "that new Frankie"? i understand you bro. i also pissed from his "ummm..."
I also didn't like the moment of his reflection after reading the letter, because there is nothing to think about when it comes to his beloved girl. However, he hated this moment in himself and if you remember how he promised to treat another guy who would treat his daughter with such a delay - he will not be lenient. Yes, it is a bit hypocritical, on the one hand, but on the other hand, he is a responsible adult and is obliged to weigh the pros and cons.
You know, I will give you advice for the future, how to read such things when shit is boiling inside you from how the MC behaves - put it aside, watch a movie, find out the latest news, just calm down, and then come back - and you may start to see things in a different light. (there is an expression "we part with the past laughing")
in the end, such works are specially made so that you think about yourself, about how you behave in your life, whether you make a mistake somewhere that can be corrected or perhaps let go of your mistake because the past cannot be brought back, so that perhaps next time you do not repeat it.
