do we already know about his ex? i dont remember

We had a small teaser flashback I think in S2’s ending?

Yeah back in high school he and his ex were discovered by the teacher I think kissing in the classroom or something ig and their parents got called and when the parents came his ex's parents put all the blessings on garam and even the ex said that it was garam that made him do all that stuff and influenced him into liking boys and yeah that hurt garam a lot
