The author never posed the ML as perfect lover. He has he dark side while MC someone who can accept that dark side. That why they are fate partner. With MC timidity, someone like ML needed in his life. Someone to guide him and give him confidence to do what they want. ML definitely a Dom. He like things to go his way while MC like when someone deeply in love with him to the point he can be controlled. It is like the conformation that his lover loves him. It gave him confidence that his lover will never fall out of love.
In reality, this type of thing happened constantly but it just they never show it to strangers or even family. Sometimes, it happened without both people realise. The common strategy is pet, love rival and family.
Never said the author posed the ML as a perfect lover. I'm referring to the literally MC calling the ML "my perfect boyfriend" Just bc these types of relationships happen doesn't mean its not toxic. Clearly MC has been manipulated and the author glossed over everything just with the excuse that they're fated partners to make it work out.
Couldn't take the art seriously as it has downgraded and when he said my "perfect" boyfriend, I legitimately rolled my eyes as he is the most manipulative, possessive, selfish character in this manhwa. And the fact that Wooseo called Jigeon's BROTHER/his best friend about his sex life after all that romantic misunderstanding between all 3 is...something. Honestly, can't remember a lot of this manhwa but I know it wasn't that great as author glossed over the manipulation and selfishness of Jigeon in a couple snaps of the fingers and all of a sudden, he's the perfect bf after only a couple weeks. HA HA!
