For a moment I thought I had Sakura figured out.... like I thought that she probably saw that the MC was being surrounded by fake as people, fake friends that would turn on him at any moment, fake girlfriend that was planning to leave him anyway; and the moment she saw that he was being drawn into that fakeness of just going with the flow then: A decided to ended it all or B thought of that plan to get him away from all those fake people still pretty crazy yandere move. But that last panel threw me for a loop hahaha It may still be the same reason but the ride sure is going to be messy
