The protagonist is surely an important character. His inner world forms the core of the story, so understanding his personality, motives and growth is key.
Another theme could be the struggle with one's own psyche. In the light novel, the character may face various internal challenges that are symbolized as 'dangers'. For example, dealing with insecurities, fears or unacknowledged desires. It's like a battle within the heart.
I heard about a guy who was climbing a tree to rescue a cat. He lost his balance and fell, breaking his arm in the process. His arm was in a really strange angle. He was in pain at first but later he told the story with so much humor. He said it was all worth it because he saved the cat. He had a long recovery period with lots of physical therapy, but he's all good now.
A hiker once tripped over a root while on a trail. He instinctively put out his arm to stop his fall and broke it. He was miles away from any help. But he managed to use his other arm and some basic first - aid knowledge to make a makeshift splint. He then slowly made his way back to the starting point. It was a harrowing experience, but he's now got a great story to tell about his survival and his broken arm.
