San E and Raina reprise their hit duet single in sequel MV 'A Midsummer Night's Sweetness: Summer Again'

San E and Raina are back together for a new song!

On July 5 KST, the rapper and former After School member teamed up to release "Summer Again," the reprise song for their 2014 hit single "A Midsummer Night's Sweetness." While the hook and melody of the song stay the same, the lyrics are now updated, with the two main characters of the original song now meeting up again after a long time for another memorable summer night.

Meanwhile, Raina was among the five After School members who reunited for last month's  'MMTG - Civilization Express's special concert. Their performances of "Bang" and "Diva" can be seen here.
