Later, I thought that the dead seagull meant Tripault Lev. At first, when he shot and killed the seagull, he said, "I will shoot myself like this soon." This seems to have been a harbinger of Tripault Lev's suicide, so in the end he committed suicide in chaos, which was expected. Tripault Lev is a very contradictory person. He first wrote to get his mother's attention and regain Nina's love, but later he "didn't know why he wrote and for whom. Without confidence, I don't know what my mission is. " When he committed suicide, he actually had published works, and he was no longer unknown, but he longed for a new form of writing, but he couldn't. He didn't know what he was writing for, so he fell into a meaningless mire. Since it was meaningless, he might as well end himself.
