Along with many stars, FT Island is now part of the UFO’s ‘FLY’ online messaging. A lot of you guys know that the celebrities are assigned a number and laptop, right?! The numbers are assigned to represent something, like birthdays, debut days, and Se7en’s ‘lucky day’. For FT Island, it’s different, their number is 3338. The FT Island boys want the fans to figure out the meaning to it! I’ll try and find some more info on this along with their video promoting this and I’ll come back to edit this post, so while you’re waiting, why not try and figure out what 3338 represents..cuz thats what i need help with! (Hint: 3 in korean also means island!)

and guess what did i get, the word Ft. SO yeah since their band name is ft island, i guess it does make sense in a way why the number 3338 has got something to do with the band. What do u think of it??
FYI: sam (삼) is three in Korean, and sum (섬) is island in Korean.. thought you should know
