CNA Lifestyle and 8Days recount that, on the evening of January 3, Jisoo hosted a private event at Haidilao in Korea, inviting 103 fans selected by raffle. The guests enjoyed unlimited hotpot refills, including premium Korean beef priced at over S$36 per serving and shrimp paste, with each table reportedly hitting around S$500, all paid by the star. Every attendee left with two clothing pieces from fashion label Self‑Portrait plus event‑only goodies like merchandise, snacks and special photo cards. Translators fluent in Chinese, English and Korean helped everyone feel included while Jisoo moved from table to table chatting with each person.
The singer also added homemade touches. Fans told 8Days she personally prepared small fruit cakes and ran a lucky draw, sending five winners home with prizes such as a Nintendo Switch, an iPad and an iPhone 17 Pro Max. At the sauce station she was seen filling an entire dish with coriander, a moment that earned her the nickname “Coriander Queen”. “We’ll copy her sauce recipe, minus the cilantro!” quipped one fan, according to 8Days. After the party, Jisoo stepped outside to meet those who had not gotten in and recorded a video singing a birthday song with them, a gesture widely praised online.

K‑pop sites like Koreaboo described the gathering as a luxurious fan party where everything was free, from the food to the high‑end tech prizes. AcademicJobs, which covered the hashtag wave, pointed to cafes, murals and charity streams organised under #OurBestGiftJISOODay in different countries, reflecting how far Jisoo’s fandom now stretches. Comments under clips from the Haidilao night repeatedly focused on her effort to speak with everyone and her decision to spend her birthday budget directly on BLINKs.
The celebrations also arrived at a busy moment in Jisoo’s career, with coverage noting her moves as head of her own label Blissoo, her solo partnership with Warner Records and talk of a new BLACKPINK era on the way. For many fans, the 31st birthday in 2026 summed up the version of Jisoo they have followed for years: a global pop star who still spends her big day sharing hotpot, fruit cake and an offbeat coriander sauce with the people who support her.
