SNSD's Seohyun has graduated from her high school. Seohyun and her fellow members in SNSD just recently made their comeback and are busy promoting their title track Oh! And even though the SNSD maknae is busy with her live promotions, she appeared on stage with TRAX and is now finding the time to attend her graduation on the 9th where she received a lifetime achievement award. "I'm excited that I'm graduating, but a part of me is a bit sad too. But I plan to become less shy and I will definitely attend my graduation," said Seohyun. After her graduation, Seohyun plans to return to Seoul immediately and resume her activities. She will also be celebrating fellow band member Sooyoung's 21st birthday as they'll be throwing their own little party in their dorm. [gallery]
