This does have romance but at most, it seems to be a romantic subplot. The romance doesn't have any huge effects on the plot. It's like showing: When the MC gets married, this woman would be his wife. It doesn't seem like it would develop into a harem since the women don't needlessly fall for him. And the fact that he has someone he likes makes him avoid sleeping with any other girls ╮(￣▽￣)╭
