Yes thank you so much!!
Saw it on tiktok,
Some sort of zombie or monster apocalypse, and its this group of teenages who were in this school, the monster/zombies got inside. The group escapes but they leave one guy behind (MC probably), the guy finds out he has been abandoned because he sees the others running across either a bus or a shed to get over the fence of the school. One of the group members looks back and sees the guy in the window, but turns around and continues running.
