Omg guys... what...

Wait why is everyone so put off by Hanjoon?? Hey at least he DID something before it's too late. He realized his feelings and ACT. I knew jin is precious, we knew it, but Hanjoon knew it too!! That's why when he felt like he was still hung up on his last love that is so hard for him, he didn't want to give a false hope to jin. He is a good adult there actually. He clearly didn't want to be a false hope to another guy that loves him dearly like his past love did to him. He knew Jin is so pure it's blinding for him. That's why he had been rejecting him resolutely. He could just have sex with jin, it's not hard for him, but he knew he was so precious so he didn't do it even when Jin seduced him. Only gave him a warning on how scary sex without love is.

Exactly because he knew how precious Jin is, the moment he realized that actually all this time, he had been captivated by Jin, he acted right away. You see, this man is very awkward at love. He only knew one painful love that he can't even understand, and was held back by them for years. As he said, he never had anyone by his side, but now he wanted to have Jin by his side. He is a beginner in love...

And people said Hanjoon's character is boring?? Why??
He is a gentlemen, good at his work, seemed very perfect but is very complicated and imperfect on inside. At one glance he seems like someone that is so cold he can't love, but he loves a man that doesn't love him back for so many years, that only treat him as sex tool. He is warm and kind, kind of lonely and sad, and he surprisingly don't know himself as well as he thought he is. I have never thought his personality as boring. I can even say he is much more interesting than most seme out there who can only fuck 24/7.

The author is brilliant for showing their personality here. Both jin and hanjoon has a vivid personality.
