Sugar, spice and everything nice. That's the formula of Apink's saccharine sweet success.
The bubbly K-pop sextet worked that formula at their first solo concert in Singapore on Sunday.
They serenaded, bopped and pouted their way into the hearts of the 3,500-strong crowd at the Max Pavilion, and also fulfilled their idol duties by declaring their gratitude to fans in endearing, stilted English, and fluent Korean, coupled with coy smiles.
Apart from the top South Korean groups such as Girls' Generation and 2NE1, few others have held full solo concerts overseas. The fact that Apink - comprising Park Cho Rong, 24, Kim Nam Joo, 19, Oh Ha Young, 18, and Yoon Bo Mi, 21, Jung Eun Ji, 21, Son Na Eun, 21 - have done so speaks volumes about their status in the industry.
Singapore is their first overseas solo gig, after selling-out tickets at their Seoul full-length concerts in January.
Apink's feminine charm was a magnet for male and female fans alike, such as a bashful teenage boy holding his school notes as well as an enthusiastic 25-year-old Caucasian saleswoman who flew in from the United States.
During the two hour and 20 minute concert, Apink obliged fans with their chart-topping pop ditties such as Luv (2014), Mr Chu (2014) and No No No (2013).
Bubblepop tunes they may be, but they are embedded with addictive hooks with great sing-along potential and, more importantly perhaps, belted out by the doe-eyed lasses while prancing around in outfits that ranged from all-white ensembles matched with knee high boots to Disney princess baby doll dresses.
The concert would be guilty of sugar overdose if not for the individual segments which showed different sides to Apink. Na Eun and Ha Young went sexy for the sultry tune Gone Not Around Any Longer, a tune originally performed by Apink's more risque counterpart Sistar19, a subunit of girl group Sistar.
The duo gyrated sensually in skin-tight black outfit, a contrast to Apink's playful dance moves - a hint of a more mature transformation to come? So far, Apink has stuck to girl-next-door since their debut in 2011.
The bright spark of the show was spunky Eunji, who shot to fame in nostalgia drama Reply 1997 (2012) and also starred in melodrama That Winter, The Wind Blows (2013). Her powerhouse vocals rang through even in the group's techno-pop dance numbers.
But it was during her solo rendition of American diva Beyonce's Listen that audiences could fully savour her impressive range.
