Actor Jung Hae-in recently held the fan meeting '2026 JUNG HAEIN FANMEETING IN JAPAN ~HAEINISM~ of the HAEINESS, by the HAEINESS, for the HAEINESS' at Tokyo Garden Theater in Japan, meeting local fans. The event was prepared as a chance for Jung and his fandom, HAEINESS, to look back on the time they have shared and make new memories together. Jung opened the fan meeting with a cover performance. As it was his first meeting with Japanese fans since the release of the Netflix series '이런 엿같은 사랑', he performed for the first time in front of fans the OST 'Begin Again', which he sang himself for the series. He then answered quiz questions about his daily life, hobbies and recent news; in the 'OF THE HAEINESS' segment he shared behind-the-scenes stories and filming episodes from the series, and in the 'BY THE HAEINESS' segment he spoke candidly about work and rest, his routines and relationships. In the 'FOR THE HAEINESS' segment, he completed missions such as push-ups and sit-ups and gave the gifts he earned to fans. Finally, he personally answered questions and messages fans had sent in advance and expressed his gratitude. Jung has recently been active with the Netflix series and the film 'Agami', and has also been confirmed to appear in 'Love Virus', set to be released on TVING in 2027.
