I think I finally figured out what bothered me while reading this (aside from the fact that he is fucking his dog lol) also, I forgot their names so it will be dog, human and red head
1- Dog just ran away like a child with no maturity to face his own mistakes and didn't comunicate his feeling is a clear way
2- Human, having issues with commitment, just jumped into the relationsip with red head disregarding any feelings dog might have
3- When they got separeted, human seemed to undertastand that dog went way on purpose, and??? he???? stil??? looked hor him????? like, he is gone, get over it, I think that's what pissed me off the most, even if they were in a normal relationship that kind of dependency is not healty at alllll it would be the best if he got his memory wiped tbh
4- Oh yeah, and while that was happening he just ignored red heads feelings until they both exploded, like you're in a relationship, at the least pretend you care
5- Red head did nothing wrong and deserves better
Conclusion: therapy for all of them would be the best answer here
This is what I think but you can disagree lol
"oh? this has updated? with the side story? oh boy, can't wait to see jooseong happy!"
*non con warning*
