On March 20, 2026, Sean posted a new update on Instagram, announcing the 'Heart Signal Running Festa'. He invited fans, offering runners a chance to chase a PB (personal best) on the course. His goal goes beyond new records: to donate to the Korea Heart Foundation. The running festa will also feature a variety of field-day style activities and food. Fans jumped in with comments like "Signed up! Donating to the Heart Foundation matters!" and rallied behind Sean's effort.
