I would fucking die. My only フレンズ are people I know on ファンポップ and ファンポップ alone. ;_; Good thing I'm フレンズ with some of them on フェイスブック and have their emails, at least like two または three emails. Still wouldn't be nearly the same, though.
I'm not sure if I'd know what to do with myself. I've had accounts here off and on for a little over 3 years now. I wouldn't have anything to do in my free time, not to mention I'd lose contact with a lot of great people.
I wouldn't care too much, it was be disappointing cause I wouldn't have that much to do, but I would get over it in like a day... find something else to do, cause I only go on here when I'm bored または yeah when I'm bored. lol.
