I Wanted a Sweet Romance, So I Chose to Play the Game Myself

[One heroine + sweet everyday romance + campus romance + pure love + romantic comedy + no System + no business] Basically, An Mo doesn't believe in real-life romance, so in pursuit of the pure love he dreams of, he plans to use himself as a model to nurture a girlfriend who writes novels and can create the kind of pure-love story he wants. But he picks the wrong person. He thinks he's only entering the game to outsmart fate, but in the end, the heroine pulls him in, heart and soul. The general outline: they start dating within the first ten chapters and meet each other's parents within the first twenty. No dragging things out and no business plot, just a sweet everyday romance. I'm terrible at writing blurbs. Anyway, that's the story. Take a look if you're interested; if not, never mind. That's it.
