This game does have romance, but it's difficult to get on either of their paths if you do not do the correct choices and actions.
It's pretty easy to get on the romance path.
The main problem of the game is different.
If you mean by using a walkthrough then sure, It's pretty easy. I guess the difference between me and other otome players, is that I look for the story instead of the romance.
It's pretty easy without using the walkthrough.
I think the story is very important but if developers claim that it's an otome game then the romance is as important as the story. Unfortunately, it seems that developers didn't work enough on the romance in this game. That's why many people complain.
