I just finished watching the kdrama and both the manhwa and the kdrama are good. But I think the kdrama is much more realistic. They added that emotional effect when Grey was at his lowest. I liked how Park Jihoon expressed Grey when he was the total opposite of his character. Truly, I cried so much at the drama. For Grey at that time, it was probably like getting stabbed repeatedly whilst holding up a boulder to avoid getting crushed, he was shouldering so much. He was at a truly pitiful state.
Guys, I recommend watching the Kdrama too!!!

Donald would have been friends with Grey. They would've talked about mathematical equations, and compete on who would solve a problem first. They would sit beside each other on every competition. I can imagine Donald pestering Grey, asking him how he solved his problem. They would talk about their past, since they suffered just as same.
Donald was a great person. Just not in the terms of personality. He was truly great and well-written. His death was too unnecessary. He could've changed.
they're so freaky and messy i love it
