We don't really know when mattbin met, there have been so many theories but the two never even said the year :( I'm pretty sure it has to be 2021 tho, just not when exactly that year. Matt went to college for a bit, so that must've been in 2020. Then he started at hybe but he never said how long he was there and when he changed to cube. In a video from May I think he told someone he's been in Korea for like 2½ years or smth and he mentioned that last Christmas was his 3rd one in Korea, so that means he has to have come there in 2021. In his boys planet profile it says that his training period was 1 year and 6 months and since they probably filled that out in like November 2022, it would mean he started training in Korea around May 2021. Again, we don't know how long he was at hybe. Bin's new agency got established in November 2021 (I think) and I've seen people say he already left cube in 2021, but that doesn't completely add up since Hyeonbin from nowadays joined cube 2022 (according to the internet) and they are close so bin must've left cube in 2022. In his bp profile his training period is 8 months, so that fits with being a trainee at studio glide since the beginning of 2022. So my guess is that they met around mid 2021. I've been trying to ask them in their lives when they met, but they never read that message, hopefully we will get more details more soon 🤞 sorry for this rant btw, just wanted to share my theories for once
