Spoiler!
Basically Taeui told Ilay he'd come back to him but Ilay couldn't hear him cuz of his loud ahh motorbike and that's where the misunderstanding happened. Taeui met with Xinlu after he escapes but when Ilay found out about this he misunderstood and got pis*** af, when he finds Taeui he did like rlly awful things to him and I'm holding a grudge against him my poor baby
I'm here to read what else would I be doing on this site?
