When You Run Into A house, Don’t Enter It

Happy's social circle was very small in his original world, and the people he contacted were few and far between as well. 

Logically speaking, when he returned to this world, the first thing he should do was to change his human communication skills and try to get into contact with more people as possible, but now, the situation was different. 

When he faced Class One Hall and the Blood Alliance Blood Robes built on his own, if he got into contact with a small group like Hunter Clan that developed on its own without the help of other places, he will just be bringing disaster to them.

In the end, either Hunter Clan was destroyed on its own, or Hunter Clan will stay far away from him. 

Happy did not wish for that to happen, so he decided to destroy the possibility of this happening beforehand.
