So this manga's portraying what ego is doing to their lives. One is a classic prince on his high horse Takahashi who can't accept that he's now down to his wheelchair, two is Togawa who is forcing the team to a higher level, then third is Nagano who just has the skills to back up his ego.
Takahashi is a roller coaster of drama. He's already getting a bit more tolerable but his character development just went back to shit lmao. Poor mom.
