Hey! There's this one novel where the ML has a friend who has a girl he sleeps with all the time. They're technically both in love with each other but each of them and everyone else thinks it's a money thing. She eventually ends up pregnant and he accidentally aborts them while in bed due to a misunderstanding. Great story, but no idea what the title is. It's not the main plot but it's one of those where it becomes the main after the actual main plot is done. Pretty sure I MTL'ed this part though. Further details: the lady runs away after the incident and the guy then accidentally finds her. He feels betrayed, angry, etc and essentially humiliates her leading her to want to kill herself. The truth eventually comes out and then he tries to get her back
