If you prefer to watch videos instead of reading the guide, feel free to do so. There is a playlist that covers an entire platinum playthrough on my YouTube channel. If you'd like and subscribe, it would mean a lot to this channel!
Our main goal during all scenes of Tape 1 is to strengthen the friendships with Autumn, Nora and Kat to achieve the status of "New Friend" at least. Please take a look at Partners in Time, Breakfast Club and Dead Poets Society if you're looking for further information. We can see the friendship status at the end of the tape.
If you have achieved the "New friend" status for all three girls at the end of Tape 1 you're good to go. Tape 2 is mainly about playing the story while picking up some missable trophies along the way. We don't need to focus on the relationships anymore, at least not in terms of trophies.
