The Dear My Haze perfume sampling at Senvers Seongsu Cafe gives a clear, source-backed look at how fragrance, books, and Seongsu’s culture-space scene came together around one ATOZ project. The documented sampling period was July 1 through July 14, with both Senvers’ official Instagram notice and Tumblbug community information pointing to Seoul Book Cafe Senvers in Seongsu-dong as the offline place to experience the scent. 1 2
That timing sits alongside ATOZ’s Tumblbug project, Dear My Haze, 그 여름의 잔향, which was listed as running from July 7 to July 21, 2025. The project page marked it as successful, with 2,557,400 won raised, 60 backers, and a 511% achievement rate. 2 For readers searching for Senvers Seongsu Cafe because of the perfume, the key point is simple: Senvers was presented as an offline sampling space for Dear My Haze during the listed July window, not as a general perfume review destination.
Dear My Haze Perfume Sampling in Seongsu

The center of this story is Dear My Haze, an ATOZ perfume project connected to the phrase 그 여름의 잔향, which can be understood naturally in English as the lingering trace of that summer. The available source material frames the scent around memory and emotion, but it does not provide a full note pyramid, bottle specification, retail price, or performance details such as longevity or projection. That means the most accurate description is not a product review, but a guide to the documented offline sampling context.
Senvers’ official Instagram notice introduced the space as an offline sampling location for Dear My Haze in Seongsu-dong and listed the sampling period as July 1 to July 14. The same notice also mentioned a related event involving a letter to a first love or sharing a story. 1 That detail matters because it places the sampling inside a soft, memory-led concept rather than a purely transactional product display.
Tumblbug’s ATOZ project page adds another anchor. Its community information stated that Dear My Haze could be sampled at Seoul Book Cafe Senvers in Seongsu-dong until Monday, July 14. 2 Since the current date is July 11, 2026, this sampling period belongs to the past. The source material supports writing about it as a completed event, not as something still open for visitors.
It is also worth being careful about what is not confirmed. The sources do not say how the perfume smelled on different people, whether visitors could purchase it at the cafe, how many samples were available, or whether the sampling continued after July 14. They do confirm the project name, the sampling location, the stated period, and the broader connection between the fragrance and ATOZ’s Tumblbug campaign.
Why Senvers Matched the Fragrance Setting
Senvers is not described only as a cafe. Shareit’s Seoul Book Cafe Senvers listing presents it as a newly opened complex cultural space in Seongsu-dong, with a concept that pairs books with music, perfume, drinks, and bakery items. The same listing says visitors can use paper books, e-books, tablets, headsets, perfume, coffee, and bakery items. 3
That helps explain why a perfume sampling could feel natural there. In the available descriptions, scent is already part of the Senvers experience, placed beside reading, listening, and cafe elements. A fragrance project built around memory and summer afterimages fits that environment more naturally than it would in a space with no connection to scent or slow cultural browsing.
A separate Shareit host page describes SENVERS through ideas such as Seongsu sensibility, a book cafe, and a personal immersion space. It also lists practical features including an exhibition and viewing area, rental equipment, 2,000 books, perfume, headsets, and tablets. 4 Those details make the venue sound suited not only for ordinary cafe use, but also for pop-up-style experiences, cultural showcases, and brand-linked sampling.
The space details also give a sense of scale. Shareit describes the venue as being in the 70-pyeong range and able to accommodate more than 100 people. 4 For a fragrance sampling tied to a funded creative project, that kind of scale is relevant: it suggests a venue large enough to host visitors while maintaining its identity as a book-centered culture space.
Practical Context for Readers
If you are looking up the location after seeing Dear My Haze or Senvers mentioned, the available basic listing places Seoul Book Cafe Senvers at 31 Achasan-ro 13-gil, Jawon Building, second floor right side, in Seongdong-gu, Seoul. The same listing gives operating hours as 11:00 to 22:00 daily and indicates that it is open year-round. 5
There is also company-context information available. Saramin, using NICE evaluation information, lists Seoul Book Cafe Senvers as a small business located at 31 Achasan-ro 13-gil, second floor, in Seongdong-gu, Seoul. The company information page names Park Hyun-young as representative and lists business areas including information services, music and record production, books, cafe operations, software development and supply, digital content production, and one-person media. The page was last updated on June 4, 2026. 6
That company profile lines up with the way Senvers appears in the cultural-space listings: it is not simply framed around coffee, but around books, media, music, scent, and digital content. For readers, this broader identity is useful because it explains why the Dear My Haze sampling appeared in a book cafe context at all.

The Dear My Haze perfume sampling at Senvers is best understood as a limited offline fragrance encounter connected to ATOZ’s successful Tumblbug project and hosted inside a Seongsu book cafe already associated with books, music, scent, drinks, and bakery. The strongest source-backed takeaway is not a claim about the perfume’s exact smell, but the documented meeting point between a memory-themed scent project and a culture space built for immersive browsing, listening, and lingering.
