Once again youthful passion beats adult reason. I love these stories. My only question was what her mother meant by wedding. I assume she told her mother that she got a boyfriend and mom jumped to wedding bells.
That's...Quite the intriguing title indeed! And I'm very happy to see the Vanilla tag together with it.
Perseverance is quite an important trait for a Hentai Protagonist indeed, and it certainly paid off for him! Just keep telling her you love her, and show it, and she finally decided to give him a chance, and he made very good use of it.
Great ending though. Haha, well, if you agree to what he just said, I can guarantee you he'll work his ass off to graduate properly and give you that wedding ceremony your parents so desperately want to see.
