Oh! Jaemi (Hangul오! 재미 ) Meaning: Oh! Fun, Also known as "Oh!Jaemi Forever" or  "Small bean bag Mod" is an additional spinoff online Multiplayer mode (Official Game Mod) running on the same engine as White Day.

It was developed by Sonnori and released in 2002 as an expansion for White Day: A Labyrinth Named School (2001), and has been featured in all of its later releases excluding v1.18 (Romance of Package version) a the servers for the game were shut down in 2005. The game can still be played in LAN (Local Area Network) mode or via Hamachi.


Oh! Jaemi is a cooperative and competitive friendly first-person shooter video game and is an extension mod of White Day. Players have the ability to modify their names and modify their controls pre-play / match. The game includes around 12 playable characters. The game supports online server play (although the server is down) and LAN Play (Local Area Network).

In this game, players do not use guns but Small bean bags instead, to fight each other. In one certain mode, each of the two teams, the blue and red team, have to compete against each other and capture bases by hitting the base points ( Large sphere with Confetti & Banner ) several time to capture it. It is unknown if there are other game modes beside this mode.

The creation of Oh! Jaemi wasn't something expected until Sonnori introduced it in updated version of White Day, perhaps to compensate for the Multiplayer Mode they initially promoted and didn't make it into the final game. It is also suggested that Oh! Jaemi was derived from the Multiplayer Mode itself as a result.

Further notes

  • Sonnorigun makes cameo appearances in this game.
  • This game is perhaps one of the initial Korean online multiplayer shooter games at the time.
  • It is running on the same engine as White Day and is an extension of it (launched via the same launcher).
  • The gameplay style is very similar to other competitive online first person shooters introduced later; such as Counter Strike or the later Metal Gear Online, the main difference is that Oh! Jaemi does not involve any guns in the game, aside from the beans, which classifies it as a friendly shooter.
  • The BGM of title screen is a part of bgm in the 'National gymnastics' of korea.
