Bunga Citra Lestari 'Ge-er' Heavy Duet with Ahn Hyo Seop, Praises the Actor's Voice

The surprises didn't stop there. The song they performed was actually sung in two languages, including Korean.

Noah Sinclair's mother expressed that she was very impressed with Ahn Hyo Seop's vocal ability, which she found to be very melodious and fitting for the song.

"For me, this is something fresh; it turns out his voice is really nice, and it fits the song well. It turns out he also likes the song and the lyrics. So, I guess it's okay to feel a little flattered," she said.

Behind the smooth performance, BCL revealed the surprising fact that they only had a very short rehearsal time.

They even just met for the first time during the rehearsal (GR) on the same day.

"I just met him earlier during the GR, we chatted a bit about everything, then how comfortable it was, how it was on stage, and that was it. But because he's very professional, everything went smoothly," she explained.

Aside from his professional skills, BCL also praised Ahn Hyo Seop's personality, which is very friendly and humble.

He even tried various traditional Indonesian foods and played the angklung backstage.

"He's friendly, very humble, and he seems to enjoy being at this event," said BCL.

Don't forget, BCL also responded to the affectionate call "Ucup" given by Indonesian fans to Ahn Hyo Seop.

According to her, the nickname sounds adorable and is easy to pronounce.

"Hahaha, it's true. But he just accepts it, right, Ucup. It's just cute for me. Just cute, maybe because it's easy to say for Indonesians," she concluded while laughing.
