Senju Hashirama Is Always Feeling Guilty

Senju Hashirama found a strange diary. Its cover was adorned with an exquisite wisteria relief, the vines winding around to form the cover design. Senju Hashirama always thought it was an ordinary diary, until one day, a line of writing suddenly appeared on the first page... "I'm exhausted today. I just hope I pass the exam, QAQ." "I'm a tree. Who are you?" Senju Hashirama changed his name and nervously wrote that line. And so, two people from completely different worlds became pen pals. Senju Hashirama envied the peaceful life in the other world, while his pen pal was very interested in the ninja world. Their daily conversations made Senju Hashirama even more determined to create a peaceful world. He and his pen pal happily exchanged stories and complaints about their lives, until one day he got so carried away writing that he wrote out his best friend's full name, and then... "Uchiha Madara? The legendary shinobi who rejected Senju Hashirama's confession of love, only to be stabbed through the heart from behind by Senju Hashirama in the end?" Senju Hashirama: !!!!!!!! "They say Uchiha Madara even said his back was sensitive, yet he was stabbed through the heart from behind. Just imagine how much he trusted Senju Hashirama. I guess that's life's greatest misfortune." This came from a clueless pen pal who had never read the manga and had only heard a selectively retold version from her fangirl best friend. Senju Hashirama: !!!!!!!! That's too much information! Give me a minute to process it! Theme:
