Since childhood, you and your rival have clashed, competed, and constantly annoyed each other. Now, in college, a strange psychological "System" activates in your mind with one purpose: to curse your rival for life.

Now, your rival must consume your saliva every day... or they will die.
How will you save their life... or torture them with the truth?
