According to KZ's management Cornerstone, the China team intially suggested a different song for KZ to perform. However, they pushed for it as KZ wants to rap in Tagalog for her first show appearance.

Although KZ and Jessie are deemed competitions on the show, the "Mahal Ko o Mahal Ako" singer got starstruck when she saw the "Price Tag" singer for the first time by accident. Jessie was on her way to the restroom when she passed by KZ's dressing room.

"The production team captured KZ’s surprised reaction and also their touching conversation afterwards... That moment, which became part of the opening scenes of 5th episode, became very endearing to the Chinese market that KZ and Jessie J became the 9th most searched in Weibo upon the episode’s broadcast," her management said.

Currently, the said episode reached the top 5 trending slot on YouTube.

As souvenirs, KZ gave all the singers a Jeepney diecast model and her CD from Star Music.
