There's romantic endings in the game but it's not like in most visual novels - The dateable characters are the princes of other kingdoms who are randomized to an extent, so the game doesn't have traditional romance routes. Rather, you get date events with your boyfriend throughout the game and depending on a few different things you choose during your playthrough you may get different kinds of outcomes regarding to your romance in the end. The endings in this game consist of a few different parts, so you can for example get the "tyrant" ending because of the choices you made in the game, but still also get a romantic & positive ending with your boyfriend :)
