I can already feel the hate but Imma say my opinion anyway. I think a lot of people are missing the fact that the idea/foundation of the story is the misunderstanding itself. You want them to clear up the issue the next chapter? Might as well change the title and synopsis. I mean ya'll saying he was stupid for running away but these kind of things do happen. Your mind goes blank and you dont even know how you got back home. This is especially true for people in a long relationship who misunderstood such "betrayal". Andddd people tend to make harsh and stupid decisions when in the grip of such strong emotions. So his reaction? Yes, it's possible.
Please stop hating the uke(/TДT)/ uwu
The plot thickens! ლ(´ڡ`ლ)
