f(x)'s Sulli has been receiving some positive attention from netizens after a note written by her to her teacher about seven months ago surfaced online recently. The note was written by Sulli on November 19, 2009 to her teacher, "Teacher~! Hello!! Hehe I think I'll have to leave first today since I have a clothes CF shoot today! Careful not to catch a cold! Take care~! ^0^~*" The note was written two months after Sulli's debut, and she undoubtedly still had some guilt about leaving class early. Netizens titled this note 'Sulli's early dismissal note that can't be refused' on online fan portals, and the sweet concern Sulli had for her teacher touched the netizens, many of whom wrote, "She's so cute; this really is a note that you can't refuse," and, "Even Sulli's emoticons are cute!" You'd have to be heartless to not excuse Sulli from class!
