It is 1000% worth reading, but it's much better if you put some work into it. For me, I think all three characters are super unlikeable but I am endlessly fascinated by the way they interact with each other. All three of them are calculating and manipulating bastards. And you can drive yourself crazy (as evidenced by the comment section) identifying reasons why Haesoo should choose one Seme or the other. Each of them have pros and cons.
It also depends on your definition of "gets good" is. I think it got really good once Joowon and Taekyung started interacting a bit more (Ch 30 ish?). How far have you gotten before dropping?
If you're looking for trope-y, fluff romance, then no. But if you're looking for a well-written story, with beautiful art, and amazing character development, then yes.
Is it worth reading? Because you know I tried to read it like three times already and dropped it those three times and I just want to know at what chapter it gets good so I can read it. ┑(￣Д ￣)┍
