This was what I was worried about when you had him lose against Gom. No drive for them and with a subpar team, it's going to have to be overwhelming from Shun, which would more than likely highlight the difference in skill between Shun and the Gom, likely changing the story and the schools they would end up going to. Even more so that Toki wouldn't be seeded. Alternatively if you had Shun won 2nd year, by the time 3rd year finals came around, people would most likely already have chosen schools so you could keep Canon fairly intact except for maybe the personalities of people. Well, too late now. I'm sure you'll be able to come up with something though the easiest way might be to go to Serbia or America for a year
Maybe do some slice of life to where shun meets the generations of miracles and how for high school they will all be going to different schools to even out the competition. Shun flat out declares he will go to where ever satsuki decides to go. Add some fluff and should help you prep for 3rd year. Especially since schools will recruit that year
Its a good point in the story for fluff chapters so no need for serious thought. Slice-of-life fantasy romance scenarios with momo, family time, beach vacation, etc... If you do want serious chapters you can have MC’s dad’s gym be competing more against Aida Riko’s dad gym but with your current stress level just do some silly romance and family time.
