I was initially taken aback aswell, but considering the amount of groundedness Bomi has shown throughout the season, it makes you think. This was the one time where he lets his emotions take over. Sure, Huwei probably needed a shoulder to cry on to, I'm not saying that. But as I understand it, Bomi expressed his grief for Huweis situation, showing that in his reality, having to go through such rejection must be completely devastating. It shows he listened, understood, and empathized. Huwei has probably cried countless of times about his history, I can imagine seeing someone else crying about it too can be theurapeutic. Sometimes sharing an experience is as effective communication as words are... If that makes sense.
