Hyunjun really was the best possible person to become Ronnie’s host. Only relying on Ronnie as a second opinion for diagnosis and constantly working to improve his own knowledge alongside utilizing Ronnie.
The reason I like this WEBTOON even more, is because he’s not using A.I to do everything! Like he himself has enough knowledge, which just helps him become even better with the A.I! It’s not like were Ronnie is the one doing everything and he’s just saying whatever the ronnie is saying.
