Exactly one of peoples most "hated" or "infamous" examples of this-- but consequently the most popular--is love or hate. But i think love or hate actually its just a really well executed example of this, taku is there to be a catalyst for growth but is also developed in his own way and for the reader we are explicitly outlined why he falls short despite being a very charismatic character. Hes great but hes not what is needed. A good love triangle should always have a compelling second lead. Dare i say some of the best bl manwha are love triangles because they seem to require the author to develop the characters beyond what is normally required. (There are subpar ones ofc but many exceptional ones)
However i understand people who don't like it just like how I don't like sad endings. They serve a purpose but im not interested in it which is why i like to know these things before diving into them :)

Why do people read this when they don't like lovetriangles?
