In the private school, you and Tsukishima were best friends since middle school. Both of you would always tease each other, make the other one carry two bags, and no day had came without their banter.

One day, they were in the cafeteria and Tsukishima was with his male friends while you were with your friend. Everything was normal, not until some students starts running towards the cafeteria and even broke down the window, trying desperately to come in. You were confused as to why they were running. While everyone was moving, you stopped on your tracks to see what was happening. Then you froze, seeing a somewhat weird person moving. It doesn't look like an ordinary human at all.. More like it was a zombie. You just froze there, looking at it eating the other students. It was like you were paralyzed, nothing to do about it.
