hello ok so here is my summary

luhan and jongin are married and have a child who's name is I think ziyu or maybe Haowen but I don't remember. 

basically jongin neglects luhan and it's gotten to the point where he started to hit luhan and punch him and kick him resulting in many bruises.

their very young son has said before that he doesn't like jongin and doesn't think of him as his dad

this fanfic is also chaptered

so sehun is their sons teacher and one day luhan has to talk to him after school so he does and that's when sehun noticing the bruises on his arm. 

sehun and luhans relationship progressing as they don't date but still go out for coffee all while sehun knows that luhan is abused by whoever at home. 

one day the beating is very bad and jongin is super angry because he thinks that luhan is cheating on him with a man who is sehun so he is very violent and luhan quickly tells his son to hide in his room and gives him his phone and tells him to play with the keychain. while luhan is severely abused by jongin their son is crying and ends up calling sehun his teacher and sehun comes to the rescue and soon the police is involved and luhan is sent the hospital and then I think that was the near end. 

wooo thankss if you help me !!!!'
