This is when he will meet his twin, they'll be both stuck in Rahman's mansion (castle iirc). So in order for them to get out, Jaeui has to make a weapon for Rahman but he really doesn't want to.
Another spoiler, Rahman and Jaeui will become a couple, there's this side story where Jaeui will visit Tay in Germany while Ilay is away (I'm not sure if he predicted his departure or it's bc he's lucky) but there he asked Tay for love advice and that's when Tay learned that Rahman is courting Jaeui. It's cute.
