In the next chapters up until the finale of season 1, their relationship goes downhill...
Cha's adoptive mother is the reason why Heeseo's mother died, yet Cha ended up siding his so-called "family" that made Heeseo go insane and stab him with a knife. (Did I made my story clear? Sorry if you didn't understand me at all. Haha) The first season went rock bottom that you're gonna remember why Heeseo did that to Cha on chapter 1.
Also, if I remember correctly, Cha told Heeseo that "he never liked/love him" on the last chapter which made the child go berserk...
We all know that Heeseo is already experiencing a lot of trauma and insecurities, but Cha protected that evil adoptive mother of his and threw Heeseo like a fucking trash.
I think the last few panels of Season 1 finale jump 7 years later? Or something like that.
Well, I love the first half of the chapter...
Ngl, I'm a sucker for Heeseo...
But even if I already read/saw the next few chapters after this, I'm still scared about what will happen...
Heeseo, my dear child.
Please protect your heart...
Don't be blinded with love, as it is not permanent... Trust me, you will get hurt soon.
