Alright, i can roughly guess where this will go.
The first 30-like chapters (or HUNDREDS of F*CKING CHAPTERS) will be full of vanillas, sweet-sweet thingy, with little to no MC Character development. Some conflict along the way, but the climax will be that the girl saying some selfish thing and break up (family issues, friend issues, her personality complex, whatever, you named it, i don't care.....well maybe a little bit), whether she really mean it or not (up to author, can't predict this).
Next the MC will finally acting like a man (first noticable development,maybe?) and start resolving things, will take 10-to-20-chapters. The girl, melted from the sincerity of MC, will go back, AND HAPPY ENDING!
Well....
