MANILA -- It appears that some local concerts are unforgettable not just for the fans but also for the foreign acts who are left in awe with the Filipino crowd's zeal.

South Korean girl group Twice has named Manila as the "most unforgettable" city they visited in their recent "Twicelights" world tour.

In a clip from "Twice: Seize the Light," a documentary series on YouTube Originals released Wednesday, the nine-piece act was asked which city they thought was the most memorable during their recent tour.

"Honestly it's difficult to choose just one city and one group of ONCE fandom that we connected with," said Jihyo, the group's leader and main vocalist, through an interpreter.

"But if I had to choose one, the Manila concert was truly memorable. We could hear the loud cheers of ONCE," she said.

The Manila leg of "Twicelights" was staged at the Mall of Asia Arena last June 29, 2019. It also marked the group's first-ever concert in the country.

"Even three hours prior to the concert, it almost felt like it was another ongoing concert because the cheers were so loud and so energetic and so enthusiastic," said Jihyo.

Jihyo added that the group "worked off" from the Filipino fans' heated response to pull off "great performances" during the concert.
