@Zherly._ I've read the novel.And the manhwa multiple times. Have to answer your question honestly he's obsessive like I would go as far as say he's the most obsessive person in bl manhwa,in good written characters terms. He's manipulative, and exttemly possessive for yohan and loves him, he does love yphan though. So he's red, just a red you'd like tho, he's not the type to hit a person or yk, typical red trash jaekyung type.
