Byun Woo-seok is turning heads with his effortlessly stylish "I-woke-up-like-this" fashion on the streets of Japan 🇯🇵—and his can't-hide-it-even-if-I-tried fangirl heart 💓 for RIIZE is making waves once again!

On June 13, Byun shared a photo dump on his social media, showing off moments from his Japan trip. And while the photos scream relaxed vibes, his attention to detail—and a surprise nod to his favorite K-pop group—made the whole look extra special. ✨

In the pics, Byun rocks a sky-blue windbreaker over a gray-toned shirt, paired with classic black pants. Add in his natural wavy hair, thin-rimmed glasses, and a "didn't-try-but-still-fabulous" baseball cap, and you've got the perfect blend of chic and cozy. 🧢🕶️

But wait—the real scene-stealer? That cap! 😮 Eagle-eyed fans noticed it's a special collab item released to celebrate RIIZE's album Odyssey. Subtle flex, but totally obvious fanboy behavior 😆💿.

Byun's not shy about his love for RIIZE either. At the 2024 MAMA Awards, he proudly said, "I've become a fan of a group—RIIZE. They're just so cool. I really want to meet them." Later, when he actually ran into the group on the red carpet, he posted a pic with the caption: "Dream come true." 📸💖

In a radio interview, he once explained how he instantly fell for RIIZE: "They sing the kind of music I love—cute and cool at the same time. And they can dance, too. I was hooked at first sight." 🎵🕺

Even in this latest photo set, he's seen highlighting the cap, casually capturing mirror selfies that radiate natural charm ✨—and the post didn't go unnoticed. It was reshared by RIIZE's official account, once again spotlighting this heartwarming fan-idol connection 🥰.

Meanwhile, Byun Woo-seok is set to return to the small screen in MBC's upcoming drama "The 21st Century Crown Princess", slated for early 2026. Stay tuned! 🎬👑
