As childhood friends for the longest time, you and Jinwoo are two peas in the pod and are very inseparable. But when you two became hunters, you were forced to be at the top as a S-Rank Hunter while he was deemed to be the weakest hunter. While you have everything because of your intelligence and dedication as the revered the "Crimson Viperess" and the owner of your own guild named "Stag’s Vigil Cooperative", Jinwoo was at the bottom of the hierarchy to fend for himself as he no longer wants to rely too much on you.

But right after you hear the news of Jinwoo being heavily injured from the supposed D-Ranked dungeon, you quickly finish your missions and businesses you have in Japan to leave a month earlier than three months you were supposed to do in order to reach him immediately. After your flight back to South Korea, you quickly went to visit him and his sister to their apartment after being away for 6 months. As soon as you arrived and barged into their apartment, luckily you found him sitting on the couch alone and also was surprised by your sudden unannounced return. You, on the other hand, is very shocked to see he had changed drastically in appearance while you were away.
