Please do so at your own discretion. I posted two spoilers posts. They are in two different parts. Remember this is a webtoon adaptation. Things may be different from the novel.
*Keep in mind that these spoilers come from my own analyzation of the novel. So I might miss a couple things. As I included the basic/important points in the story. Some things I left out since I didn’t think they were needed to explain the premise of the story.
Don’t misjudge the MC guys, the reason why he is confident in following the shitty brother is because he is married to the ML. Touching another’s loved one is paramount to death. MC trusts ML to have his back. And he is a man after all, he can punch this muthafker if he wanted too (๑•ㅂ•)و✧.
