I need to check if this is a known manga or anime. A quick search shows that "Miya-chan no Kyuun Life!" is a manga by Miku Shiro. It's a slice-of-life comedy about the daily adventures of two middle school girls, Miya and Akane. The series is known for its adorable art style and light-hearted humor. Each issue would focus on different episodes in their friendship. Episode 17, then, would be one of the chapters or volumes in the ongoing series.
