what did it mean in the chapter when he said “it’s a missile”?

I feel like he was so bored with his everyday life and hated everything that he needed something to excite him, even if it was as effed up as getting kidnapped and everything that happened to him. Like the missile that he wished would bomb his school. And now we see he's bored again but with Soyeon coming back into his life, he finds that happiness again. The "missile" to make his life exciting again.

ohhh okay ty
