ML & MC are no different. MC did the same thing to ML(they dated in high school) and spreaded 'em (photos)where it reached to ML's hospitalized mom(later she died). And ML got persuaded to the point to get revenge. 
Later in the story there is nothing but 🍇🍇🍇🍇🍇🍇🍇🍇🍇 no character development in ML and he even forced the MC to have seggs with a dog🙂. The story is totally seggs,🍇,seggs,🍇and so onnnn. There is no hint of love between 'em. And MC will get traumatized to the tip of mt everest. If you're looking for some development in characters it only happens in side stories.
