On June 4, TWICEs Tzuyu and Sana held a live broadcast on V Live titled TWICE Sana Tzuyu X LieV.
When it was Sanas turn to recommend a summer song, she chose SISTARs Loving U, saying that summer is SISTARs season. The LieV broadcast was held on the day SISTAR had their final music show performance on Inkigayo, leading the two TWICE members to naturally talk about SISTARs disbandment.
Sana explained, This week was also our last week [promoting with Signal], and we got a chance to promote at the same time as SISTAR. It was really nice to see them perform their songs in real life.
