Probably not, the manhwa I usually read is about Murim or something like Legendary Moonlight Sculptor.
I just found out about your masterpiece and finished it today. This has to be the visual novel I've been looking for. I know there won't be any sex in this game, but having some sweet times with the girls is not going to hurt. For instance, you may add hugging, cuddling, kissing,... I don't know; you name it.
