Why joowon is still toxic? Someone care to explain?

He's toxic but he's toxic because he's trying to protect Haesoo from getting hurt. We can't deny that Taekyung/Taku has a reputation for just using his models and then leaving them. Joowon maybe toxic but he's al protective. If anything I think Taku's toxic because he's obsessed with Haesoo. He's obsessed about Haesoo's looks and Haesoo can do for him and ONLY him whereas Joowon actually does love Haesoo but can't due to their forbidden relationship and tbh Haesoo's no longer innocent when it come to him and Joowon. In fact, Haesoo toys with Joowon's feelings by pissing him off on purpose.
