He gives the examples of, "We'd go out to movies and the amusement park. She said the thrill rides were too scary for her...she vetoed all the action and horror flicks."
He says it was a girlfriend he had back in middle school, but we don't actually know how old he was. As he was probably somewhere around 13 to 15, it makes sense that he wasn't super conscientious at the time.
He says that her friends coming after him was "the worst part": "That's when I learned a valuable lesson: romance is way more trouble than it's worth!"
It is fascinating that out these 22 characters between the ages of 16 and several-hundred-years-old, the only confirmation we've had of anyone being in a relationship before is a first-year student!
In the original game Ace says that he has a lot more fun spending time with his male friends, but this was made slightly more vague on EN, into, "chillin' with my buds."
