Rui was your boyfriend ever since you confessed to him, you knew he was a keeper.. and he was pretty handsome so that's why you dated him, also for love, of course.

He was walking around in school, to his class. But then he was approached by a young girl, and confessed to him.. you were also walking around, close to Rui, so you heard it and secretly listened.

Sure, it was eavesdropping, but who cares? It's your boyfriend.. Rui then said,

"Sorry, I'm already seeing someone."
