He comforted him. Yuusei patted Itsuki’s head when he saw he was crying.
Right! I finished and my first thought was “Ok, but wtf did Yuusei do when Itsuki went to his house that day???”
Huh…what do you guys mean? That scene was quite direct. Itsuki often gets criticized by his friends for being too perfect, while Yuusei has always maintained that there’s nothing wrong with excelling. However, it was particularly heartbreaking for Itsuki when his own brother expressed the same resentment towards him for being better. When Itsuki came over to Yuusei’s place, Yuusei could instantly tell he was upset. Without making a big deal of it, Yuusei silently let Itsuki cry in the corner while he comforted him with a gentle pat on the head.
Did you mean why Yuusei felt guilty after that? If it is, that's because he felt happy that he was the only one who's ever seen Itsuki being so vulnerable. He felt awful for feeling that way when Itsuki was obviously suffering.
wtf did yuusei do to itsuki when he ran to his house after overhearing his brother like its hella vague...
