Sakura The cruel events that mess with people's emotions and make them say hurtful things to people they care about. ;.; She'd like the fluffier events, like the puppies and kitties one.
Fai Something like the Tokyo event, or something else that attacked people physically. But he doesn't like it when the world brings up bad memories, like with the ghost event (he doesn't like his students being messed with). He actually kinda enjoyed the Tweak event though, not counting what happened to his room.
Chun Hyang The ghosts of the past event. That was just low and she hates Kiseki for taking advantage of her, and other people's, feelings for their loved ones to upset them. She'd probably like the puppies and kitties event. Or something that made Mong Ryong not flirt with other girls.
