In my understanding Jeonghan is thinking that Kangwoo doesn't really love him because tge second one don't want them to be seen in public.. J was the one who confess his feelings and K accepted because he didn't want to push J away. K never really realized his feelings for J until he lost him. But J was already to tired after 8 years relationship.
I read some many bad comments about J but in my opinion he just want to be loved and show his love to everyone..
Is a natural thing for people to get hurt when your are hiding your relationship.
They both deserve better than that. And obviously I prefer them apart than being again together..
Is tike for them to take different ways.
I found that story realistic as no one will accept being in a relationship for 8 years with someone who don't show his love to you ..

Can I ask why does it look like that Kangwoo was the pathetic one in the relationship in the past?
What was the sole reason why the white haired dude broke up with him? How and why did Jeonghan dumped Kangwoo? Why?Whe?WHE???
Spoil me I can take it
