It would be interesting if the two main characters don’t get together. In my scenario the guy falls in love with another coworker and the female mc regret it.
This sound like a shoujo with the trope of the jerk with a golden heart. The reason this series is popular is because of yuri. The love rival is toxic and if she was a male people wouldn’t like this manga.
White knights are scum defending this type of behavior is pathetic. The girl is a manipulative psycho taking advantage of a poor guy who is probably depressed.
