They're not the same person...
do you have info on this? the art styles are so so similar I would be rlly surprised if this is true
I don't have proof, but just like you, you also can't prove that they are the same person based on artstyle. They both have different names (Gaepi and Hobaen) and each of them have their own Twitter account that they post their art to....(which I don't think looks similar, but that's just my opinion). I doubt they would use all their time and energy to be pretend to be two different people, publishing comics under two different names. A lot of artstyles can look similar. But that doesn't mean they are one person pretending to be two... That's like so much work, considering that both Bongchon Bride and Mr. 100% Perfect are pretty popular. If they were the same person, why bother pretending to be two people when they could just publish everything under one name and enjoy the success of both stories?
this is def the same artist as 100% perfect (author churning out BANGERS) but I wonder why they changed their name
