Either the mf director will kidnap Dan or use grandma to blackmail Dan (I forgot to add to the theory) something he will do to create a crack that will lead Dan to push jaekyung away that indirectly will affect on his performance. 
I HOPE JAEKYUNG SEE THE MF AND BEAT THE SH** OUT OF HIM (my hands are itching to beat him since last time) but then I think Dan might stop him cuz it will affect his public image before match for beating a citizen
I'm so restless now..so many theories which one will come true CAN'T WAIT FOR NEXT CHAPTER

See , told you all in previous chapter, now they are on it to divert jaekyung focus from match. Jaekyung from his previous match was aware they will try to use Dan as bait thus kept him to stay home if not necessary don't got out (he don't want Dan to be hurt in his rivalry 😭). 
I two got theories now regarding the upcoming scenario
The director will make Dan manipulat him with his  past make it so...Dan feel be little or maybe offer something ( I'm pretty sure he won't offer anything because jumin coach knows how loyal Dan is with his job) all of it will create tranch between them the indifference will make jaekyung anxious and lose focus 

Second theroy is my personal favourite cuz it make more sense with respect to genre and breaking of "jinx" (trauma/insomnia) Director will kidnap Dan, since the match due tomorrow jaekyung need szx to win (jinx he always believed in) The inability of Dan and match pressure, things will become intense this time jaekyung will show up with his jinx being unhadled and win the championship title on his own (while the cops will find Dan and director doc will expose everything about jumin) now the reason I like this theroy is the win will be symbolic and the end of jaekyung's "jinx" (actually is past trauma he suffered after witnessing his father death) suffering  that played as midium/reason to bring Dan and him under one roof , since the jinx will break and jaekyung will be free from his fear Dan's wish for jaekyung to recover from insomnia will fullfill too and a beginning new destiny fro jaekyung as he get on his knees to ask Dan to marry him. 
Jaekyung is need to be reminded there is was not jinx he won even when his Dan was alive it's just a trauma from not able to prove his worth to his dad ,he need to get over the trauma for himself and his love of life. (it's time for the jinx to demolish) same happened with jiwoon in BJ Alex. 

Jaekyung from his previous match has learnt the lesson that they (jumin and his coach) are capable of doing anything to win (remeber the chapter jumin said "we will use any means to win") that doc director has seen Dan and him together and jaekyung knows were well jumin know Dan has came back to gym. Jaekyung in order to protect Dan is keeping him away from gym so Dan won't end up like a bait for them again. 
This chapter is distressing , jaekyung is going through a toughest phase mentally and emotionally, jumin is provoking him using his past so jaekyung loose control/focus and cause scene so they could win easily. Jaekyung past was already broken him the empire he built was snatched from him everything right now they are using to distress him But what broked him emotionally most is when his life is falling apart at house he saw even Dan is egar to leave him (the one he shared the broken side with he buried ages ago) 
Behind his harsh words I can hear his heart scream "EVRYONE LEFT ME! YOU ALSO WANT TO LEAVE! Please ..I DON'T WANT TO BE LEFT BEHIND!"  He want Dan to by his side but he can't confess his feelings instead like a hurt child he showed as if he don't care if Dan leaves (just say it man you both can't live without eachother) 

I CAN'T TAKE IT JAEKYUNG JUST WIN AND CONFESS YOU FEELINGS ALREADY. MAKE THOSE MF PAY FOR THEIR DEEDS

"I don't want to say this but I believe granny's death will play a big role in bringing dan and jaekyung closer when dan will be left alone in this world having no one to call family and love jaekyung will take him under his wings embracing him with warmth." 
 A part of theory I made in chapter 52 year ago is coming in effect I guess. (whole theory is in 9th section of chapter 52 if anybody wish to read it)

Dan will be happy if jaekyung choose win championship over him because if jaekyung choose Dan over championship and give up on everything he worked so hard to achieve Dan will forever live with guilt. (there is nothing more admirable for Dan than watching jaekyung hand raised up in Win) remember the chapter when Dan saw jaekyung win the look of admiration. I believe jaekyung will Win and announce his retirement after this match ON LIVE broadcast and step down to focus on his relationship with Dan and be more active trainer training training future fighters and expand his gym by including the kids programs into gym (remember in S1 coach said jaekyung didn't accepted kids program in gym) it is mentioned in plot thus I believe he will accept the proposal of coach as a new start. He is too young to retire yet I think he will cause throughout his life his aim was to make it out big and defeat the poverty but now he got a new reason in life (there gotta to be something in your life as important as winning) he have it now It's Dan. 

It's all I think, right now the championship title is a symbol of triumph of good over evil hope those mf pay for all the shaddy stuff they did especially for falsely accusing Dan and all pain misery both went through jaekyung win will bring justice to Dan. That director Doc will surely run out of business loan sharks will loom over his head thrash him and he will end up in slums. Just like Dan had to because of him. 

Last but not least I hope he propose Dan one beach ( It's not a want IT'S A NEED) HAPPY BEACH MOMENT

Coach namwook don't bring Dan up otherwise bro will become full fledge drunkard
bro's wife ran away and you are rubbing salt on his wound

 Jaekyung it's for you betterment in order to trigger your true feelings out

So this is What I think 
Remember when jaekyung saw the bruise on Dan arm from IVE drip and got worried it turned that he got scared and mistook the bruise for drug injection marks ( the PTSD he carried from his father incident)  the long term impact it left on him I feel bad for him 
I like making things extra painful for my self

As far I guess junmin (that buzz cut MMA fighter) has some beef against jaekyung and knows him since jaekyung's rookie days. And I think he moved to Seoul maybe something big happen like death maybe his father died or something.

Bro !! The prediction i made for future plot in chapter 52 in nov 2024 is  really coming true. About Dan giving could shoulders to jaekyung by pushing him away and jaekyung traumatic past showing up time to time. Few things haven't came true yet but you can read that comment it's in 52 chapter in 7th section of comment with @Rb Handel. 
I'm happy lol 😂

Those tears in his eyes while suppression his dignity he really suffered through out life 
But How could you laugh at his face after looking at his tears da** jaekyung da** 
once you fall in love with him you will regret making him cry

Don't worry Dan this supper expensive apartment will soon be your home once you change this mf jaekyung , this mf Better approach Dan for heart and not for his got da** jinx ( I'm at verge of killing him)

When Dan said " it's not like I'm the best in the field then why is he paying such high sum" I legit screamed because that basterd wants to use you for his own good 😭😭  I was glad Dan found his offer suspicious too.
