I don't exactly het what happened there, but Alice looks like she's trying to stop the bleeding rather than stabbing Marisa or something. The gaze also looks more like horrified "OHSHI- what happened to my Marisa?!" than the classic "yan yan" empty look.
Turns out Marisa was trying to cook up some Italian as a surprise dinner for the two of them, but it wasn't as easy as she excected and she had to lie down a bit.
Justy said: I don't exactly het what happened there, but Alice looks like she's trying to stop the bleeding rather than stabbing Marisa or something. The gaze also looks more like horrified "OHSHI- what happened to my Marisa?!" than the classic "yan yan" empty look.
We need the artist tag to be sure, but I do not believe this is a yandere thing this guy has drawn other works with Marisa hurt.
My guess is Marisa went out came back hurt badly, Alice wanted to take care of her or was just utterly stunned. Marisa then holds Alice's hand and says something along the lines of "don't worry" with a smile. Since she Marisa moved her hand from Alice's face I assume she is collapsing.
