Hearts2Hearts at the Seongsu 2aN Pop-Up: What Happened at ‘2aN School in Seongsu’

The Hearts2Hearts Seongsu moment centered on 2aN’s pop-up store, officially titled ‘2aN School in Seongsu.’ The event has now wrapped: 2aN operated the pop-up from April 17 to April 26, 2026, at Seongsu LECT on Yeonmujang-gil in Seongdong-gu, Seoul.¹

For fans, the key highlight came just before the official opening. Hearts2Hearts attended the pre-opening photocall on the morning of April 16, 2026, at LECT, giving the beauty pop-up an extra dose of entertainment buzz.² The appearance connected the group with 2aN’s brand world at a moment when the company was using the Seongsu space to introduce visitors to its ‘Love, Rosy Collection’ in a more physical, hands-on way.³

The April 16 photocall was reported as part of the opening celebration for ‘2aN School in Seongsu.’ Ajunews described Hearts2Hearts as attending the event at LECT in Seoul’s Seongdong-gu, and its photo caption identified eight members posing together: Yeon, Stella, Yuha, Ian, A-na, Jueun, Carmen, and Jiwoo.²

That member lineup matters because pop-up coverage can sometimes focus only on the brand or the venue. Here, the group’s presence was a central visual moment in the event’s media rollout. NewDaily also reported that Hearts2Hearts posed at the 2aN pop-up opening event in Seongsu LECT on the same morning, tying the group’s appearance directly to the pop-up’s launch period.³

If you came across the phrase ‘Hearts2Hearts Seongsu,’ this is the specific context behind it: not a standalone concert or fan meeting, but a branded beauty pop-up appearance linked to 2aN’s spring makeup promotion. CMN later described Hearts2Hearts as the brand model attending the April 16 pre-opening event, one day before the pop-up’s official public run began.⁴

What ‘2aN School in Seongsu’ Was Built Around

The pop-up was not simply a photo area attached to a product display. The concept was ‘2aN School,’ with the space arranged around 2aN’s new ‘Love, Rosy Collection.’ Fashionbiz reported that the event included product testing zones, a math zone, an art zone, and a DIY custom Dual Cheek program.¹

That school-themed structure gave the pop-up a clear lifestyle angle. Instead of asking visitors only to look at products, the brand shaped the experience around moving through themed areas. For a color makeup brand, that kind of setup makes sense: blush tones, texture, shade matching, and packaging details tend to work best when people can see and compare them in person.

2aN CEO Kim Shin-young described the pop-up as “a space where visitors can directly experience spring-season makeup through the ‘Love, Rosy Collection.’”¹ The quote is short, but it captures the brand’s practical goal: the Seongsu store was designed to turn a product collection into an offline experience.

The offline angle was also emphasized in other coverage. Reports noted that the pop-up was planned to expand consumer contact points after the ‘Love, Rosy Collection’ drew a response following its Olive Young launch.⁵ In other words, the Seongsu location served as a bridge between retail attention and a more immersive brand encounter.

Why the Seongsu Setting Fit the Moment

Seongsu has become a natural setting for pop-ups because it supports a mix of beauty, fashion, design, and entertainment traffic. The source material does not provide visitor numbers or sales results, so those should not be assumed. What is clear is that 2aN chose Seongsu LECT on Yeonmujang-gil for a limited ten-day run, and several outlets treated the opening as a noteworthy beauty and celebrity-facing event.¹

The timing also helped shape the story. The official pop-up dates were April 17 through April 26, 2026, while the Hearts2Hearts photocall took place on April 16, 2026.² Because the current date is May 23, 2026, it is more accurate to talk about the event in the past tense. The pop-up has ended, and CMN reported on May 5, 2026, that 2aN had completed the ‘2aN School in Seongsu’ event.⁶

That wrap-up coverage added a few more details about the look of the space. CMN reported that the pop-up used the peach-pink color tone of the new ‘Love, Rosy Collection’ and included collaborative elements with the design studio Bloomingtail.⁶ Those details help explain why the event worked as a visual media moment: the pop-up had a defined palette, a playful school concept, and a celebrity photocall featuring Hearts2Hearts.

For readers catching up after the event, the main takeaway is simple: the Hearts2Hearts Seongsu pop-up story was a brand appearance at 2aN’s ‘2aN School in Seongsu,’ held around the ‘Love, Rosy Collection’ at Seongsu LECT. Hearts2Hearts helped bring attention to the April 16 pre-opening photocall, while the public pop-up itself ran from April 17 to April 26, 2026. It was a compact beauty-culture moment where idol visibility, makeup testing, and Seongsu’s pop-up scene came together in one carefully staged space.
