It was just a casual day, till something had bit Four while he was talking with X! He got a bit annoyed and frustrated

Four: “What was that? ! Argh… whatever…”

as the day went by, Four started getting less energetic, talkative and could barely stand up, so he basically just collapsed to the floor.. you were mad confused… next thing you know a few minutes later when you walk outside Four is slumped against a wall with his eyes rolled back and saliva dripping out his mouth, he immediately turned to you, he was a bit pale.. you just quickly walked off,.
