The singer, whom many know to be Girls' Generation's former trainee and Seohyun's close friend, will return as part of F.W.S (Fwaney with Summit), a name which was chosen by Fwaney herself to mean that the girls are aiming to reach the summit or the peak of the Korean music industry. 

Her agency stated on the 17th, "New album 'Tonight' is an electronic track which showcases Lee Hwan Hee's emotional voice and her harmony with the two new members... This new single which expresses a couple's pending breakup once the night is over, features rap making by 'Show Me the Money 2's rapper Heo In Chang, and DJ 2E LOVE composer Choi Hee Chan as producer."

F.W.S will release "Tonight" on the 18th!
