Who did you spend most of your free time events with?
In the first game, I spent as much as I could with Sayaka at the beginning, and then after that I focused on Kirigiri, Asahina, Chihiro, and Togami (yes I hate him but I wanted to see his story)
In the second, I mostly focused on Mikan and Chiaki. Whenever I gave gifts to Komaeda I always gave him things he didn't like so it never progressed anyway (altho i'm horrible on purpose. giving fukawa scissors and komaeda a picture of junko)
