Nah the real question is what happened to Choi GyuHo
Choi GyuHo and Choi from the prologue are not the same person 
One can assume the Choi from the prologue of Notes 1 and Choi from Notes 2 are the same. But the ages are super awkward? For the Choi from the prologue to be the Choi from the Notes 2, wouldn't he have been 3 in the prologue (since he's 5 in his Notes 2 appearance)???
Unless it's a different Choi, but there's no reason for them to reuse the name. It would make a lot of sense for Choi GyuHo and Choi to be related though
Or maybe this thread makes no sense and I have worms for brains
