im tryna find this one fully coloured apocalypse with main characters being in the millinery force of smth bl webtoon. The white-haired ML injected mc with some freaky medicine under the ruse of it being a cure or another excuse and during the mission they did the freak while trapped by the building with zombies surrounding them before getting saved by a helicopter. It was a short story but i need to reread it so bad pls help
