After Izuku treatment Momo never left indicating she loves him from the start and they started dating since then
Todochako
Shoto and ochako started to date after they got into UA during the sports festival.
Katuski x CamieKatuski and camie also started to date during the festival as they got caught having sex as Izumomo wanted to do the same thing and the Izumomo couple went to go to another room.
I might do 3 seasons in this story who knows and ofc Rei will divorce Endeavor All might will divorce Inko. Rei will be keeping the kids as they see Izuku as a brother like shoto and Inko will be pissed that Izuku ruined the family knowing that her and Izumi started it
