[Hot Spring] Oozora Subaru was caught by her kouhai sticking her butt out at the onsen

Oozora Subaru recounts a hot spring trip with Nekomata Okayu. Subaru admits she does weird poses like sticking her butt out when she thinks no one's watching. However, a kouhai later told her they were at the same onsen, causing Subaru to scream in embarrassment at the realization she was being watched the entire time without knowing.
