I think it went something like that. He know the boy going to be one of the strongest. He went to gift the boy with lots of stuffs to make good a impression.
Cannot remember which chapter the boy appeared. They only had brief encounter.
He shud be the "original" hero of the novel our MC transmigated into, i think. And yes they met as the person described above.
but that was only a brief encounter?, jeez how did it escalate like that HAHHAHHA
can anyone remind when did that blue haired kid appear??!! hahahaha
