I think Jaeha really and truly loved her but he's gay and needs sex with guys? Or something like that.
She's the only one he ever loved. Everyone else, it seems are just sextoys to him. Friends with benefits but he never informed them of that at the onset.
Yet, when Eunho starts to back away he can't deal with it and drags him back.
If he needed the dick that badly, but he loved her...why not bring in pegging? Or make it an open relationship? Why not be upfront about things?
I wonder how the divorce went and why it happened. Maybe she met someone else?
I think he tried with Heeson (I think that's how her name is written) have "a normal relationship". I think that he struggled in the past with the fact that he's gay (for me he didn't accept that and it's still an issue for him in the present... But characters are still in development so this is just my POV) and with Heeson he saw an opportunity to be "in the right path" of life. But obviously it was just living in denial, he's all in for dicks! (Dude don't be troubled by it, dicks are goooooodddd! ლ(´ڡ`ლ)
Now getting serious, it's sad, he tried, he failed, she was totally in love with him (I think she loved him, like really loved him) but he couldn't make it work. That's why he feel guilty and can't move on, because he couldn't avoid the huge fact that he's gay and nothing, not even a good, kind, beautiful and "head over heels" for him woman changed that. Maybe she realized that at the end and she was the one who left, but I'm almost certain that he was the one who step aside and surrendered.
But again, this is my interpretation, I really love this story because even if it's fiction, it has some sense of realism.
How did you write everything that I thought of while reading the manga? Are you reading my mind? (≧∀≦) Haha
On a more serious note, I really love how this manga is realistic somehow, Jaeha is trying to hide his real self and be "normal" just like how real people would, Eunho knows Jaeha has slept with someone else and while it bothers him he didnt rape him or manipulate him like seme's in other mangas would, all characters here are portrayed realisticly and I love the mangaka for this
"Is terrible love that YOU are walking with spiders..."
Man that hurts... I try to stay in the line in understanding Jaeha, but dude, sometimes I want to punch his face so hard (๑•ㅂ•)و✧
But I'm kind of proud of my boy Eunho... He's just so honest and he actually knows more about Jaeha than he thinks he doesn't at all. He recognize that Jaeha loved her (btw I think she's sweet and also she's a victim of Jaeha's complicated way of be) and he tries to give him some space for him to drown in whatever self pity pool of bullshit (Sorry I'm a little mad at Hyung)
Actually all of them are victims, really (Eunho, Hanjun and Heeson) he's like a hurricane that leave disasters on its walk!
But then, he came feeling sorry and being charming and UGH! I feel you Eunho...
Thanks to random fujoshis for your dedication. I love this work so much!
