At that time he was discussing to become a model, but as far as I know at least, he had no serious attempt in that direction. What happened in the end, and without any particular subtlety, was cockroach.
In the narrative, the character contemplates pursuing a career in modeling, though it appears he never genuinely committed to that path. His discussions suggest interest, but there is a lack of serious action behind them.
Ultimately, the situation unfolds rather plainly, leading to an unexpected and perhaps unappealing outcome represented metaphorically by a cockroach. This suggests a sense of disappointment or a stark contrast to his earlier aspirations.
