21-09-2026
The hashtag is trending because a major entertainment company released a teaser today announcing the first large-scale concert by the popular Thai pairing WilliamEst. The event, titled Reign Together Concert, is scheduled for December 5 and 6, 2026, at Impact Arena in Muang Thong Thani, with further details promised the following day.WilliamEst consists of actors William Jakrapatr Kaewpanpong and Est Supha Sangaworawong. They rose to wide fame through the 2024–2025 boys’ love series ThamePo: Heart That Skips a Beat and have since built a dedicated international following through fan meetings and a sold-out two-day fan concert in Bangkok in 2025.The new teaser uses a cinematic royal concept with imagery of colliding worlds, castles, and swords. Fans immediately interpreted the visuals as a prince-and-merman or dual-kingdom story and responded with excitement, jokes about a royal wedding, and praise for the production values. The announcement marks a step up from earlier fancons to a full arena concert, which is why the hashtag exploded across social platforms this morning.
