Chaehyun Seo onsights Gorilas en la Niebla (8b+)

Chaehyun Seo, who last week sent a 9a+, has onsighted Gorilas en la niebla (8b+) in Oliana. At age 16, she won four World Cups and two years later she became the World Champion. This year she was runner up in the overall World Cup.
Can you tell us more about the onsight?
I tried it after just one warm-up! I planned to try harder routes for the project, but this morning was too foggy and humid, so I just tried an easier route for fun. I didn’t expect an onsight because the weather was too bad, and the last part was a bit wet. The holds were super slippery because of the humidity.
